A point object transvers half the distance with velocity V⁰. The remaining part of the distance is covered with velocity V₁ for the half of the time and which velocity V₂ for the rest half. The average velocity of the object for the whole journey is –

Let “s” be total displacement, then s/2 = V⁰ t₁ or t₁ = s / 2V⁰ and, s/2 = V₁ t₂ + V₂t₃ = (V₁ + V₂) t₂ To find, Average velocity = Total displacement / Total time (should be ...

An object travels 24 m with a speed of 4 metre per second and another 32 m with a speed of 8 metre per second. The average speed of the object is

Time travel to cover 24 m with the speed of 4 metre per second, t₁ = 24/4 = 6 s Time travel to cover 32 m with the speed of 8 metre per second, t₂ = 32/8 = 4 ...

A bridge is 400 m long. A 150 m long train crosses the bridge at a speed of 50 metre per second. Time taken by the train to cross it:

Total length of path covered by train = 400 + 150 = 550 m Train to cross the bridge (Find, Time Taken) = Total distance / speed = 550 / 50 = 11 s
