A 59 kg gymnast jumps upward from the top of a platform with a speed of 3.5 m/s. They land on a trampoline a distance of 2.5 m below the top of the platform. How fast is the gymnast moving when they reach the trampoline? How far do they depress the trampoline, assuming it behaves like a spring with a spring constant of 6100 N/m?
