Question

A worker pushes a box with a horizontal force of 50. 0 n over a level distance of 5. 0 m. If a frictional force of 43 n acts on the box in a direction opposite to that of the worker, what net work is done on the box ?.

Answer 1

7N

Step-by-step explanation:

Since the forces are working in opposite directions, you substract i.e

50.0N - 43N = 7N
