A car starts from rest and accelerates at 5 m/s^2 . At t = 4s, a ball is dropped out of a windown by a person sitting in the car. What is the velocity and acceleration of the ball at t = 6s?

A car starts from rest and accelerates uniformly with 2 ms^(-2) . At t = 10 s, a stone is dropped out of the window 1 m high of the car. What are the (i) velocity, and (ii) acceleration of the stone at t = 10.1 s? (Neglect air resistance). Take g = 9.8ms^(-2) .

A truck starts from rest with an acceleration of 1.5 m//s^(2) car 150 m behind starts from rest with an acceleration of 2 m//s^(2) . How long will it take before both the truck and car side byside, and how much distance is traveled by each?

A helicopter takes off along the vertical with an acceleration a = 3m//s^(2) and zero initial velocity. In a certain time the pilot switches off the engine. At the point of take off, the sound dies away in a time t_(2) = 30 sec . Determine the velocity of the helicopter at the moment when its engine is switched off assuming that velocity of sound is 320 m/s.

An electron, starting from rest and moving with a constant acceleration, travels 2.00 cm in 5.00 ms. What is the magnitude of this acceleration ?
