George has a body mass of 'm' kg runs up a slope inclined at an angle . When he reaches a vertical height 'h' m, his speed is 'V' m/s. What is the total work done by George by then? Peter, also has a body mass of 'm' kg, performs the same task as George. If George completes the task in 12 seconds and Peter in 15 seconds, who will be more strenuous? Why?   Neglect all losses.
