Answer:
Explanation:
Energy store in the compressed trampoline = potential energy of at the maximum height ignoring friction
energy stored in the trampoline = [tex]\frac{1}{2} kx^{2}[/tex] where k is spring constant and x is the distance compressed = 0.5 × 2900 × 0.38² = 209.38 J
209.38 J = 25 × 9.8 × h
h maximum height attain = 209.38 J / ( 25 × 9.8) = 0.855 m
