The work done on a slingshot is 40 J to pull back a .1kg stone. If the slingshot projects the stone straight up in the air, what is the maximum height to which the stone will rise?

OpenStudy (mazefordays090):

about 60 ft

The work done on the stone, 40 J, is converted to potential energy, reaching a maximum of m g h when the stone velocity is zero at the top of the trajectory. So, 40 J = m g h make sure the units are consistent.

I don't understand how the work done on the stone converts to potential energy. Is it because KE(lowest)=PE (highest)?

OpenStudy (anonymous):

Yes.

Okay. Thank you.
