Module 5: Impulse and Momentum Topic 4 Application: Conservation of Momentum in Collisions 3.A 0. 1 kg golf ball initially moving at 10 m/s strikes and bounces back off a 5 kg bowling ball initially at rest. The momentum of the bowling ball after the collision is less than 1 kg m/s b. equal to 1 kg m/s C. greater than 1 kg m/s d. more information is needed to determine the momentum after the collision 4. A fly encounters the windshield of a speeding car. Which experiences the greater change in momentum? e . The car The fly g. They are the same h. It depends on the speed of the car 5. Car A moving to the right has a perfectly inelastic collision with car B moving to the left. Immediately after the collision, the combined wreckage is seen to move to the left. From this we can determine: Car B was moving quicker than car A Car A was lighter than car B K . Car B had more momentum than car A Car A felt a greater force from the collision than car B Long Answer. Answer the following questions, showing all work. 6.A 2000 kg train car moving at 3 m/s links with a 3000 kg train car initially at rest. What is the speed of the cars after the collision? 8.A 4.8 kg bowling ball moving at 10 m/s strikes a 1.6 kg bowling pin, initially at rest, head-on. The pin flies forwards at 15 m/s after the collision. m. What is the final velocity of the bowling ball? n. Is this an elastic or inelastic collision? (Show your work to justify your answer.) 9.A ball (m,) of mass 0.440kg moving east with a speed of 3.30 m/s collides head-on with a 0.220 kg ball (m2) at rest. If the collision is perfectly elastic, what will the speed of each ball be after the collision? (Hint: the relationship of the velocities before and after the collision is V1- V21 = Var - Vil. This equation may be useful if you have two unknowns in an equation.) o. Solve for Var in terms of vir using the provided information. p. Using the law of conservation of momentum, substitute your answer from part (a) and solve for the final velocity of the first ball q. Solve for the final velocity of the second ball. whro
