Question

(6%) Problem 9: A student jumping on a trampoline reaches a maximum height of h = 1.37 m. The maximum height is measured from the surface of trampoline in its unstretched position. The student has a mass of m = 72 kg. Randomized Variables h = 1.37 m m = 72 kg 50% Part (a) What is the student's speed immediately before she reaches the trampoline after the jump in m/s? 50% Part (b) If, when she lands on the trampoline, she stretches the trampoline down d = 0.75 m, what is the spring constant k in N/m of the trampoline?
