Question

There is block on the surface with the friction of 35N. An external force applied on this mass and the block travels 5m. If the

external force is 50N, the total work of the system is:

Answer 1

The total work of the system is 175 J.

The formula for work is W = F * d, where F is the force and d is the distance. In this case, the force is 50 N and the distance is 5 m. Therefore, the total work is 175 J.

Note that the friction force is not doing any work, because it is acting in the opposite direction of the displacement.
