Picture yourself at a trampoline park, or on a trampoline in a backyard.

While trampolines are fun, they can also be dangerous. Let's say you collide with a 64 kg

person on the trampoline as seen in the diagram below. You are going the velocity you

calculated at 50.0 cm above the surface of the neutral position of the trampoline.

mass 'you' = 55kg

velocity once your feet just leave the trampoline surface = 7.00 m/s

velocity at 50.0 cm above the surface of the neutral position of the trampoline = ??? (I got 6.26 m/s)

mass 'them' = 64kg

their initial velocity = 8.33333 m/s

their final velocity = 16.67 m/s

1. Calculate your final velocity.

2) Was this collision elastic or inelastic? Give both mathematical and conceptual

explanations.

3) Does this abide by the conservation of energy? Explain.
