A weightlifter raises a 90k-g barbell from the floor to a height of 2/2 m in 0.6 s. What was his average power output during the life?

  • Physics - ,

    Do you really mean 2/2 m ? That equals 1 m.

    Do you really mean during his life? Does he ever stop?

    You need to type the question properly if you want the right answers.

    Divide work done (potential energy increase, in this case) by the time interval to get power.
