An external force of 6N is applied on body at rest at time t=0, at t=1 sec direction of force is reversed. Find the speed of body when it comes back to the initial position

A force of 10 N is applied to a body at rest for 3 sec. The velocity of the body becomes 2 m/s. Find the mass of the body.

When an external force is applied to a body, the change in length per unit original length along the direction of force is called
