The impulse-momentum theorem relates impulse to the change in momentum. 3. You throw a 400 g lump of clay at 10 m/s against a wall. The clay sticks to the wall. What is the initial momentum? Final momentum? Impulse? 4. You throw a 400 g rubber ball at 10 m/s against a wall. The ball rebounds at 8 m/s. What is the initial momentum? Final momentum? Impulse? 5. Given this, is it better for a car to come to a stop or bounce back in a collision?
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?

8.) In this photo, a fire extinguisher provides the impulse for a hallway rocket cart. Which is NOT true about the motion of the rocket cart and person? a.) The cart and person are propelled as a result of gas from the fire extinguisher pushing against air in the room. b.) The force of the gas on the cart and person is equal and opposite to the force of the person and cart on the expelled gas. c.) The momentum of the cart and person is equal in magnitude and opposite in direction to the momentum of the expelled gas.
1. Calculate the magnitude of the impulse during the collision. 2. Calculate the magnitude and direction of the velocity of the 4.0 kg cart after the collision. 3. Calculate the mass m of the second cart
