Physics..Urgent!!!

posted by on .

In the sport of pole vaulting, the jumper's point of mass concentration, called the centre of mass, must clear the pole. Assume that a 59 kg jumper must raise the centre of mass from 1.1 m off the ground to 4.6 m off the ground. What is the jumper's potential energy at the top of the bar relative to the point at which the jumper started to move?

    P.E. change = M*g*(change in H)

    can you please show step by step what to do with solutions
    thanks it would be great help

    This is a one step problem. Use the formula I provided to calculate the Potential Energy change at the top of the jump.

    so i did Ep=Mg (hf-hi)
    =59(9.8)(4.6-1.1)
    =2023.7 J

    is this right
