A certain motor is capable of doing 3000 joules of work in 11 seconds. What is the power output of this motor?

Starting from rest, a woman lifts a barbell with a constant force F through a distance h, at which point she is still lifting, and

the barbell has acquired a speed v. Let Ewoman stand for the following energy terms associated with the woman:
