Question

When the applied force is 150 N and the friction is 94 N, what is the net force? A. 56 N B. 244 N C. -56 N D. -244 N

Answer 1

Useful force (56 N) = force applied (150 N) - force lost to friction (94 N)

+56 N will be applied for acceleration, etc. - the frictional force is in opposite direction the the applied force
