Question

A body of mass 2 kg initially at rest moves under the action of an applied horizontal force of 7 N on a table with coefficient of kinetic friction = 0.1. Compute the
(a) work done by the applied force in 10 s.
(b) work done by friction in 10 s.
(c) work done by the net force on the body in 10 s.
(d) change in KE of the body in 10 s.

Answer 1

c. work don't by the net force on the body in 10s

Answer 2

The answer is 10seconds
