A body is moving on a rough surface with an initial velocity of 5 m/s and a constant force of friction equal to 6N acts on it. If the mass of body is 2kg, find the K. E. of body after 1s.

Explanation:
However, the magnitude of the friction force itself depends on the normal force, and hence on the mass of the block. between the object and the surface is just its weight, which is equal to its mass multiplied by the acceleration due to earth's gravity, g.
