Calculate the velocity of a moving body of mass 7 kg whose liner momentum is 5 kg ms^(-1)

Calculate the force acting on a body whose linear momentum changes by 20 kg ms(-1) in 10 s.

Calculate the kinetic energy of a body of mass 0.1 kg and momentum 20 kg ms^(-1)

Calculate the net force acting on a body of mass 10 kg moving with a unifrom velocity of 2 ms^(-1) .

With the application of a force of 20N, the momentum of a body of mass 2kg changes from 16 kg ms^(-1) to 24 kg ms^(-1) . Then

Two bodies of masses 3 kg and 4 kg are moving along X axis. At a time t, the bodics are at a distance of 2 m and 3 m from the origin and has velocities of 2 ms^(-1) and-3 ms^(-1) . Calculate the position and velocity of centre of mass. What will be the total momentum of the system?

A body of mass 5 kg moving with a velocity of 6 m s^(-1) collide with another body of mass 2 kg which is at rest. Afterwards they move in the same direction as before. If the velocity of the body of mass 2 kg 10 ms^(-1) , find the velocity and kinetic energy to the body of mass 5 kg.
