###### Question:

A boy fires the 0.2-lb marble at the wall striking it at B. h 5ft, 0o 45°, and d 75 ft. a) Plot the marble trajectory before and after it strikes the wall for the case where vA 50 ft/s and the coefficient of restitution is e NOTE: This requires solving two projectile motions, one before impact and one after impact. With vA- 50 ft/s, plot the trajectories after the impact for at least five different coefficients 0.5. b) of restitution c) How do the changes in the coefficient of restitution, e, affect the plots? VA
