Momentum of an object changes from 100 kg m/s to 200 kg m/s in 2 seconds. What is the force applied to it?

A force of 200 N is applied to a body and its velocity changes from 5m/s to 10m/s in a second. What is the mass of the body?

A 10 kg weight is accelerated from rest to 20 m/s in 1 sec. What force acts on it:

A man holds a 10 kg box 2m above the ground.What is the work done?

A force of 1000 Newton is applied on a 25 kg mass for 5 seconds. What would be its velocity?

Which has the unit kg m/s

The speed of a car weighing 1500 kg increases from 36 km/h to 72 km/h uniformly. What will be the change in momentum of the car?

The position of an object moving along x-axis is given by x = a+ bt^2 , where a = 10m, b = 3 ms^-2 , and 't' is measured in second. What is the average velocity between t = 2s and t = 4s?

If the distance between two bodies of mass 200 kg each is 3 meters, what is the force of gravitation between them?

The momentum of a body is given by vecP = (10t^2hati + 5thatj) kg-m//s . Find the force acting on the body at t = 2s.

A hockey ball of mass 200 g travelling at 10 m s^-1 is struck by a hockey stick so as to return it along its original path with a velocity at 5m s^1 . Calculate the change of momentum occured in the motion of hockey ball by the force applied by the hockey stick.
