A 12.0 kg package is released from rest down a 30.0" chute. When the package reaches the bottom it undergoes a perfectly elastic collision with a 24 kg stationary package, giving this second package a speed of 7.82 m/s. Assuming the chute is frictionless, what height must the first package have been released from? Question 2 A 5.61 kg bowling ball is dropped 1.66 m onto a large spring. If the bowling ball compresses the spring by 0.415 m, what must the spring constant of the spring be? A 12.0 kg package is released from rest down a 30.0" chute.
