The 4-kg sphere is projected horizontally with a velocity of 13 m/s against the 18-kg carriage which is backed up by the spring with stiffness of 1720 N/m. The carriage is initially at rest with the spring uncompressed. If the coefficient of restitution is 0.66, calculate the rebound velocity v', the rebound angle 8, and the maximum travel 6 of the carriage after impact. 4 kg Answers: V= 9- 8= 13 m/s i i 0.85 180. 0.25 0 k 1720 N/m 69⁰ 18 kg m/s m
