Chapter 11, Problem 6P(choose chapter or problem)
Big Air A new generation of pogo sticks lets a rider bounce more than 2 meters off the ground by using elastic bands to store energy. When the pogo’s plunger hits the ground, the elastic bands stretch as the pogo and rider come to rest. At the low point of the bounce, the stretched bands start to contract, pushing out the plunger and launching the rider into the air. For a total mass of 80kg (rider plus pogo), a stretch of 0.40 m launches a rider 2.0 m above the starting point. Assuming that the elastic bands stretch and store energy like a spring, how high would the 80 kg pogo and rider go for a stretch of 0.20 m? A. 2.0 m B. 1.5 m C. 1.0 m D. 0.50 m

ANSWER:Solution In this problem we have to find the height. Before solving this problem we have take data of given values. Data: Height reached by rider=2 m Stretch of the string=0.40 m Mass of the rider=80 kg Potential energy means energy difference between the energy of an object in the given position and a at the end position where it wil
