what would happen if 15 joules of work is done on an object that has 90 N of force applied to it

Answers

Answer:

The magnitude of the force is given by F = ma = (10)(5) = 50 N. It acts over a distance of 20 m, in the same direction as the displacement of the object, implying that the total work done by the force is given by W = Fx = (50)(20) = 1000 Joules.
