What power must be delivered to the object by the force?

Question

A 10-N force is needed to move an object with a constant velocity of 5.0 m/s. What power must be delivered to the object by the force?

Answer 1

Power = energy/time= force*dist/time=force* velocity

Power = 10*5 = 50 Watts  (or 50 Joules/sec)

Answer 2

Power = force x velocity

          =10 x 5

          =50 W
