Question

A child has a mass of 18kg and slides down a height of 2.7m without friction. the gravitiational energy is equal to zero at ground level.

1) write an expression for the childs total mechanical potential energy E at the top of the slide in terms of the variables given and the acceleration due to gravity g.

2) what is the change in the childs potential energy from the top to the bottom of the slide at ground level (I.e delta U = U ground-U top)

3) what is the childs final speed?
