the potential energy is 10 times as much
... PE = m g h
the kinetic energy is also 10 times, but velocity is squared in KE
10 times KE means √10 times velocity
Olympic diver performs a dive from the 10 m platform and achieves a speed of 14 m/s just before entering the water. Neglecting air friction, approximately how many times larger the diver’s speed than the diver would have achieved by performing from a 1 m platform? How much more potential energy does the diver have from the 10 m platform than on a 1 m platform?
