To calculate the kinetic energy of a body given its mass and momentum, we can make use of the relationship between momentum (p) and kinetic energy (K.E.).
Step 1: Write the formulas
– Momentum (p) is given by:
p = mv
– Kinetic energy (K.E.) is given by:
K.E. = (1/2) mv²
Step 2: Relate momentum to kinetic energy
We can write kinetic energy in terms of momentum:
Using the relation p = mv, we can rearrange to find v:
v = p/m
Substituting this into the kinetic energy formula:
K.E. = (1/2) m (p/m)²
K.E. = (1/2) (p²/m)
Step 3: Substitute the values
Given:
– Mass (m) = 2 kg
– Momentum (p) = 2 N·s (Note: momentum is in kg·m/s which is equivalent to N·s)
Now substituting into the formula for kinetic energy:
K.E. = (1/2) (p²/m)
K.E. = (1/2) [(2)² / 2]
K.E. = (1/2) [4 / 2]
K.E. = (1/2) [2]
K.E. = 1 J
Final Answer:
The kinetic energy of the body is 1 J.

A body of mass 2 kg is placed on rough horizontal plane. The coefficient of friction between body and plane is 0.2 Then
To find the motion of the body placed on a rough horizontal plane, we need to consider the effects of friction and applied force. Given: Mass of the body (m) = 2 kg Coefficient of friction (μ) = 0.2 Acceleration due to gravity (g) = 9.8 m/s² (we will use 10 m/s² for simplicity) Step 1: Calculate theRead more
To find the motion of the body placed on a rough horizontal plane, we need to consider the effects of friction and applied force.
Given:
Mass of the body (m) = 2 kg
Coefficient of friction (μ) = 0.2
Acceleration due to gravity (g) = 9.8 m/s² (we will use 10 m/s² for simplicity)
Step 1: Calculate the normal force (N)
On a horizontal plane, the normal force (N) is equal to the weight of the body:
N = m * g
N = 2 kg * 10 m/s²
N = 20 N
Step 2: Find the maximum static friction (f_s)
The maximum static friction is given by:
f_s = μ * N
f_s = 0.2 * 20 N
f_s = 4 N
Step 3: Analyze the applied force (F)
Case (a): If F = 5 N
– The applied force (5 N) is greater than the maximum static friction (4 N).
– Hence, the body will move in the forward direction.
Case (b): If F = 3 N
– The applied force (3 N) is less than the maximum static friction (4 N).
– Thus, the body will not move and will remain at rest.
**Case (c):** If F = 3 N
– Since the applied force is not enough to overcome friction, the body will remain at rest.
Conclusion:
– For F = 5 N, the body will move in the forward direction.
– For F = 3 N, the body will remain at rest.
– Hence, both (a) and (c) are correct.
Final Answer:
The correct options are both (a) and (c).
