An elevator weighing 5000 kgf is moving upward and tension in the supporting cable is 50000 N. Find the upward acceleration. How far does it rise in a time of 10 seconds starting from rest ?

A body starts from rest moves with constant acceleration p. Find the ratio of the distances travelled by the body in 5 seconds and 5th second.

The total mass of an elevator with a 80 kg man in it is 1000 kg. This elevator moving upward with a speed of 8 ms^-1 is brought to rest over a distance of 16 m. Calculate the tension T in the cable supporting the elevator

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 motorboat starting from rest on a lake accelerates in a straight line at a constant rate of 3.0 ms ^(-2) for 8.0 s . How far does the boat travel during this time?

A wheel rotates with a constant acceleration of 2.0 rad//s^2 .If the wheel starts from rest,how many revolutions will it make in the first 10 seconds?
