physics - power(1)

posted by .

A grocer lifts an 8.0-kg carton from the floor to a height of 0.80 m in 5 sec. Calculate the power of man.

  • physics - power(1) -

    Have you learned that
    Work = Force x distance?

    Have you learned that
    Power = Work/Time ?

    Put them both together for the answer.

    The force is the weight, which M g.

    These are things you should know by now.
