a skaterboarder is moving 5.25 m/s when he starts to roll up a frictionless hill. how much higher is he when he comes to a stop? (energy problem)

Question

anonymous · Answer

this is basic energy problem. equate kinetic energy to potential energy. $$v ^{2}/2$$ =$$g*h$$ solving you get h =1.4048m

a diver is on a board 1.80m above the water. she jumps straight up at 3.62 m/s. what is her maximum height above the water?

anonymous · Answer

this is similar to the previous one, the only differenc is that you have to add 1.80 to the final answer. then final answer will be 1.8 + $$3.62^{2}\div(2*9.81)$$ = 2.46
