Answer #1

impulse = F * t = m ( Vf - Vi )

                      F * t = Pf - Pi

impulse is zero .............. The net force on the object must be zero.

                                             The momentum of the object may change, but it starts and ends with the same momentum

1. For an object moving in uniform circular motion, does the centripetal force do work on the object? A. Yes, because work is force times distance and the object is moving from the force. B. No, because the force is always perpendicular to the object's displacement. C. No, because the displacement of the object is zero. D. Yes, because the object is moving. 2. An object is moving along a straight line with a speed of v when it hits...
