complete the following 3 steps. 1. Indicate what your chosen system is (which objects are included in the system?) as well as your initial and final instants. Explain how your choice will help you solve the problem. 2. Draw a momentum-impulse bar chart for your chosen system that is consistent with the information given. 3. Write an equation using the bar chart as a guide and solve for any unknowns. A 6-kg bowling ball moving at 3 m/s hits a single 2-kg pin, knocking it forward at 6 m/s. If the collision took 0.050 s, what average force was exerted on the pin?

IM-6 Stanley pitches a 0.375kg baseball that travels with a speed of 27.0m/s to the right toward David. David swings the bat and hits the ball with a vertical force of 80.0N that lasts for 0.200s. Before impact: The hit: 27.0m/s 80.0N a) Sketch on your paper the vectors for: the momentum before impact PB, the change in momentum Ap, and the momentum after impact pA. Clearly label each vector as pB, pA, or Ap. b) Calculate the final momentum of the ball PA. c) Show on your figure the angle of the final momentum from the horizontal and find the value of that angle.

A Z Olaf is standing on a sheet of ice that covers the football stadium parking lot in Buffalo, New York; there is negligible friction between his feet and the ice. A friend throws Olaf a ball of mass 0.400 kg that is traveling horizontally at 10.8 m/s. Olaf's mass is 69.7 kg.( Figure 1) 2 masteringphysics.com/mycitemView?assignment ProblemID=189028758&offset=next W S Figure X command A # 3 20 E D C $ B 4 888 R F I % 5 of V 254 FD T G 6 B Part A 20 If Olaf catches the ball, with what speed ty do Olaf and the ball move afterward?
