Question

9 m1 m2 Figure 3: Diagram of simplified Newton's cradle. The two balls have equal mass and b1 s dropped from height, h, while ball 2 is stationary 3. In the simplified Newton's cradle drawn in Figure 3 270 g. Bal 1 is dropped from h=10 mm. The length of the connecting cords is L=75 mm and the connections are spaced such that when stationary, mass 1 and mass 2 are touching at equal heights e.g. h- a. If the coefficient of restitution is e1, what is the velocity of mass 2 after impact? b. If the coefficient of restitution is e=0.99, what is the work done by the impact on the system? c. If the coefficient of restitution is e=0.99, how many impacts will occur before the system is stationary again?
