A lift is moving down with an acceleration of `3ms^(-2)`. A ball is releasd 1.7 m above the lift floor. Assuming `g=9.8ms^(-2)`, how long will the ball take to hit the floor ?

A truck starts from rest with an acceleration of 1.5 ms^-2 while a car 150 metre behind starts from rest with an acceleration of 2 ms^-2 . How long will it take beforeboth the truck and car side by side, and how much distance is travelled by each?

A person in an elevator accelerating upwards with an acceleration of 2ms^-2 , tosses a coin vertically upwards with a speed of 20 m s^-1 . After how much time will the coin fall back into his hand? (g = 10 ms^-2)

A boy standing on a stationary lift (open from above) throws a ball upwards with the maximum initial speed he can, equal to 49 m s^-1 . How much time does the ball take to return to his hands? If the lift starts moving up with a uniform speed of 5 m s^-1 and the boy again throws the ball up with the maximum speed he can, how long does the ball take to return to his hands ?

A ball is thrown up with a speed of 9.8 ms^-1 What the acceleration while the ball is moving downwards.

A ball is thrown up with a speed of 9.8 ms^-1 What the acceleration due to gravity at the top most point.

How much force will be required to produce an acceleration of 4 ms ^(-2) in a ball of mass 6 kg ?

A bus is beginning to move with aceleratino of 1 ms^-2 . A man wo wants to board it can run at 9 ms^-1 . Show that he3 can catch it in 8 sec., if he is 40 m behind when it starts.

The earth's gravitational force an acceleration of 5ms^-2 on a 1kg mass somewhere in the space. How much will be the accleration of a 3kg mass at that place ?
