A body of mass 5 kg is moving along a straight line with a velocity of 1 ms−1. The external force acting on the body is:
A body of mass 2 kg is moving on a smooth floor in straight line with a uniform velocity of 10 m/s. Resultant force acting on the body is:
A force of 1N acts on a body of mass of 10kg. As a result, the body covers 100cm in 4seconds moving along a straight line. Find the initial velocity.
