A 6.64 kg object is initially traveling in the positive x-direction at 9.44 m/s. It collides with a 7.85 kg object that is initially at rest. The two objects are in contact for just 14.7 ms. After the collision the 7.85 kg object is observed to move in the positive x-direction at 7.95 m/s. What is the average net force that acts on the 7.85 kg object during the 14.7 ms?
