A body of mass 2 kg is at rest. What should be the magnitude of force which will make the body move with a speed of 30 m/s at the end of 1 s?

A force acts for 0.1 s on a body of mass 2 kg initially at rest. The force is then withdrawn and the body moves with a velocity of 2 m/s. Find the magnitude of force.

A force acts for 0.1 s on a body of mass 2.0 kg initially at rest. The force is then withdrawn and the body moves with a velocity of 2 "m s"^(-1) . Find the magnitude of the force.

A 60 kg body moving with speed 12 m/s collides inelastically with another body of mass 50 kg moving in same direction with speed 2 m/s. After collision the 50 kg body moves with a speed of 10 m/s. The value of coefficient of restitution (e) is :-

A force acts for 0.1 s on a body of mass 1.2 kg initially at rest. The force then ceases to act and the body moves thorugh 2 m in the next 1.0 s . Find the magnitude of force.

A body of mass 5 kg initially at rest is subjected to a force of 20 N. What is the kinetic energy acquired by the body at the end of 10 s?

A body of mass 3 kg at rest is acted upon by a force and the body moves through a distance 20 m in 5 s. Force on the body is
