1. Average speed = Total distance / Total time taken
2. Average velocity = Total displacement / Total time taken
Let’s start with the given information:
– Joseph jogs from A to B, a distance of 300 meters, in 2 minutes 30 seconds.
– Then, he turns around and jogs back 100 meters to point C in another 1 minute.
(a) Average Speed and Velocity from A to B:
1. Average Speed from A to B:
Speed = Total distance / Total time taken
Total distance from A to B = 300 meters
Total time taken from A to B = 2 minutes 30 seconds = 2.5 minutes
Speed = 300 meters / 2.5 minutes
Speed = 120 meters per minute
Therefore, Joseph’s average speed from A to B is 120 meters per minute.
2. Average Velocity from A to B:
As Joseph moves from A to B in a straight line, his displacement is the distance between the initial and final points.
Displacement from A to B = 300 meters (since he returns to the starting point, there’s no net displacement)
Total time taken from A to B = 2.5 minutes
Velocity = Displacement / Total time taken
Velocity = 300 meters / 2.5 minutes
Velocity = 120 meters per minute
Therefore, Joseph’s average velocity from A to B is 120 meters per minute.
(b) Average Speed and Velocity from A to C:
1. Average Speed from A to C:
Total distance from A to C = 300 meters + 100 meters = 400 meters
Total time taken from A to C = 2.5 minutes + 1 minute = 3.5 minutes
Speed = Total distance / Total time taken
Speed = 400 meters / 3.5 minutes
Speed ≈ 114.29 meters per minute
Therefore, Joseph’s average speed from A to C is approximately 114.29 meters per minute.
2. Average Velocity from A to C:
Joseph’s displacement from A to C accounts for the net distance covered in a straight line.
Displacement from A to C = 300 meters (distance from A to B) – 100 meters (distance from B to C)
Displacement from A to C = 200 meters (in the direction from A to C)
Total time taken from A to C = 3.5 minutes
Velocity = Displacement / Total time taken
Velocity = 200 meters / 3.5 minutes
Velocity ≈ 57.14 meters per minute
Therefore, Joseph’s average velocity from A to C is approximately 57.14 meters per minute.

Given:
– Speed during the trip to school = 20 km/h
– Speed during the return trip = 30 km/h
To determine the overall average speed, we use the formula:
Total average speed = Total distance / Total time
Assuming Abdul travels the same distance to and from school:
Calculation:
Let’s denote the distance to school as ‘D’.
– Time taken for the trip to school = Distance to school / Speed to school = D / 20
– Time taken for the return trip = Distance to school / Speed of return = D / 30
The total time for the entire trip:
Total time = Time to school + Time for return trip
Total time = D / 20 + D / 30
Now, the formula for total average speed:
Total average speed = Total distance / Total time
Substituting the expression for total time:
Total average speed = 2D / (D / 20 + D / 30)
Simplify the equation:
Total average speed = 2D / ((3D + 2D) / 60)
Total average speed = 2D / (5D / 60)
Total average speed = 120 / 5
Total average speed = 24 km/h
Hence, Abdul’s average speed for his entire round trip, accounting for both the journey to school and the return trip, is calculated to be 24 km/h. This indicates that considering his varying speeds in both directions, Abdul maintained an average speed of 24 km/h throughout the entire journey.

(i) Uniform Acceleration:
Uniform acceleration refers to the motion of an object where its velocity changes at a constant rate over equal intervals of time. In simpler terms, it means that the object’s speed increases or decreases by the same amount in each equal interval of time. Mathematically, this translates to a consistent change in velocity per unit of time.
Characteristics of Uniform Acceleration:
1. Constant Change in Velocity: In uniform acceleration, the change in velocity remains constant per unit of time.
2. Equal Intervals of Time: The object experiences identical changes in velocity during equal intervals of time.
3. Linear Relationship Between Time and Velocity: The relationship between time and velocity is linear in uniform acceleration scenarios.
Example: An object moving in a straight line under the influence of gravity near the Earth’s surface demonstrates uniform acceleration as its velocity increases by approximately 9.8 m/s every second.
(ii) Non-Uniform Acceleration:
Non-uniform acceleration describes the motion of an object where its velocity changes irregularly, either increasing or decreasing, at a non-constant rate. In this case, the object’s speed changes by different amounts during equal intervals of time.
Characteristics of Non-Uniform Acceleration:
1. Varying Rate of Change in Velocity: In non-uniform acceleration, the change in velocity per unit of time is not consistent.
2. Unequal Intervals of Time: The object experiences different changes in velocity during equal intervals of time.

(i) Uniform Acceleration:
Uniform acceleration refers to the motion of an object where its velocity changes at a constant rate over equal intervals of time. In simpler terms, it means that the object’s speed increases or decreases by the same amount in each equal interval of time. Mathematically, this translates to a consistent change in velocity per unit of time.
Characteristics of Uniform Acceleration:
1. Constant Change in Velocity: In uniform acceleration, the change in velocity remains constant per unit of time.
2. Equal Intervals of Time: The object experiences identical changes in velocity during equal intervals of time.
3. Linear Relationship Between Time and Velocity: The relationship between time and velocity is linear in uniform acceleration scenarios.
Example: An object moving in a straight line under the influence of gravity near the Earth’s surface demonstrates uniform acceleration as its velocity increases by approximately 9.8 m/s every second.
(ii) Non-Uniform Acceleration:
Non-uniform acceleration describes the motion of an object where its velocity changes irregularly, either increasing or decreasing, at a non-constant rate. In this case, the object’s speed changes by different amounts during equal intervals of time.
Characteristics of Non-Uniform Acceleration:
1. Varying Rate of Change in Velocity: In non-uniform acceleration, the change in velocity per unit of time is not consistent.
2. Unequal Intervals of Time: The object experiences different changes in velocity during equal intervals of time.
3. Non-Linear Relationship Between Time and Velocity: The relationship between time and velocity is not linear; it may follow a curve or exhibit varying rates of change.
Example: A car’s motion during its journey where it accelerates, then decelerates, and later accelerates again showcases non-uniform acceleration due to its varying rates of change in velocity over time.
In summary, uniform acceleration demonstrates a consistent and constant change in velocity over time, while non-uniform acceleration showcases irregular changes in velocity, either increasing or decreasing, over equal time intervals.
