Question

A tow truck pulls a 3500 kg mazda car out of the mud. The car is moved 20 M in 4 seconds by the truck. What is the work done by the tow truck

Answer 1

W = F * S one does not know the work performed because one does not know what force produced the resulting work. Neither can one calculate the power required because P = W / t (work / time)

One only knows the distance and the time but not the force required.
