A force F is applied on a body (which moves on a straight line) for a duration of 3 s. The momentum of the body changes from 10 g cm/s to 40 g cm/s. The magnitude of the force F is

A 10 N force is applied on a body which produces in it an acceleration of 1 m//s^(2) . The mass of other body is

If a force is applied at an angle to a body moving along a straight line:

A force is applied on a body of mass 0.9kg that is at rest. The force is applied for a duration of 5s and as a result the body covers a distance of 250 m. Find the magnitude of the force.
