The 7-kg sphere is projected horizontally with a velocity of 19 m/s against the 35-kg carriage which is backed up by the spring with stiffness of 1730 N/m. The carriage is initially at rest with the spring uncompressed. If the coefficient of restitution is 0.75, calculate the rebound velocity v', the rebound angle 8, and the maximum travel 8 of the carriage after impact. 7 kg 10. 19 m/s k= 1730 N/m 57° 35 kg
