A 5 kg ball is initially at rest at the top of a hill 10m high. If it rolls down the hill (converting all of its potential energy to kinetic energy,) what is the maximum kinetic energy it could have at the bottom of the hill?


-I am not sure what formula to use?

  • Physics -

    wait just figured it out pe=mgh

  • Physics -

    the KE will equal to the initial PE, mgh
