A pogo stick is a children’s toy that consists of a hollow tube with footrests and a spring inside. Riders compress the spring by bouncing on it, then the expanding spring hurls them into the sky. A particular pogo stick has a 35 kg rider who can compress the spring by 0.33m. What does the spring constant have to be for her to be bounced upward by 1.0m from where the spring is totally compressed? A. 3200 N/m B. 6300 N/m
