A 500, k, g,500kg pumpkin is dropped 15, m,15m on top of a school bus.
a) How much gravitational potential energy was gained when it was winched up 15, m,15m?(75000 J)
b) Assuming all of this GPE is turned into kinetic energy as the pumpkin drops, work out its speed as it hits the school bus.
c) Would the speed be any different for a 5, point, 0, k, g,5.0kg pumpkin?
