A body of mass `2kg` starts from rest and moves with uniform acceleration. It acquires a velocity `20ms^-1` in `4s`.
Find average power transferred to the body in first `2s`.

A body of mass 2kg starts from rest and moves with uniform acceleration. It acquires a velocity 20ms^-1 in 4s . The power exerted on the body at 2s is

A body starts from rest and then moves with uniform acceleration. Then.

A body starts from rest and moves for n seconds with uniform acceleration a, its velocity after n seconds is v. The displacement of the body in last 3 seconds is :

A motor car, starting from rest, moves with uniform acceleration and attains a velocity of 8 ms^(-1) in 8 s. It then moves with uniform velocity and finally brought to rest in 32 m under unifrom retardation. The total distance covered by the car is 464 m. Find the acceleration.

Starting from rest a car moves with uniform acceleration and attains a velocity of 72 kmh^(-1) in 15 s. It then moves with uniform speed for 20s and is then brought to rest in 10 s undere uniform retardation. Find total distance travelled using velocity - time graph.

A bus starting from rest moves with a uniform acceleration of 0.1 m//s^(2) for 2 minutes. Find (a) the speed acquired, (b) th distance travelled.
