resistance.) (4 points)
B. How much force must the ride produce to do this?
C. How much work does gravity do as the riders are lifted up to a height of 50 meters?
D. How much work does gravity do as the riders are lifted up to a height of 50 meters?
E. What is the potential energy of a single, average weight person at the top of the ride?
F. If the ride slows from its maximum speed at 30 m/s to zero in 2 seconds, how much power did it take? Use the combination mass of all 15 riders
