Formula Sheet Question Completion Status: Question 3 3 points Save Answer 18 In the follwoing situation two objects had a collision but we don't have any infor mation regarding their velosities before and after the collision. If these tw ball were in touch for t= 0.015 s, and the applied force from each was F = 25 N, can you calculate the amount of change in the momentum for each one? V1 V3 V2 V4 99 P2 - P1 = 0.375 O P2 - P1 = 0 O P2 - P1 = 1666.67 we can't calculate based on this information.

Question Completion Status: Question 4 3 points Save Answer A ball (m= 0.2kg and V1 = 8 m/s) is moving toward a wall ( V: O) and after a collision, returns with V2 = 2 m/s (Opposite direction) CD Photo by NASA image Library 13 R 7 O a. What is the momentum before and after collision? b. Is it an elastic or inelastic collision? Why? a) p( before) = 1.6 kg m/s p(after) = -0.4 kg m/s b) it's an elastic because Kinetic energy is constant before and after collision a) p( before) = 1.6 kg m/s p(after) = 04 kg m/s b) it's an inelastic because velocity of the ball changed after collision. a) p( before) = 1.6 kg m/s p(after) = -0.4 kg m/s b) it's an inelastic because Kinetic energy is not constant before and after collision a) p( before) = 1.6 kg m/s p(after) = 0.4 kg m/s b) it's an elastic because Kinetic energy is not constant before and after collision SEP 4': Sun 25 Sep 2 29 I' Safari File Edit View Histow Bookmarks Window Help A: Sun 25$ep 2 30 (0') New Tab H bb-gbc'blackboardcom ' Content Course Outline Remaining Time: 1 hour. 22 minutes, 16 seconds.
