A boy weighing 40kg runs at 8.0m/s grabs a rope and swings of level ground. What maximum height does the child reach?

How do I solve this?? it is under the conservation of energy section of work, power and energy.

any help would be great! thanks

Assume his KE is transformed to gravitational potential energy.

• Physics -

how do i find gravitational potential energy without being given the height?
