Question 1 1/1 pts In a game of billiards, the cue ball strikes the 8-ball and immediately comes to rest. What happens to the cue ball’s momentum? Correct! It is transferred to the 8-ball. It stays with the cue ball. https://onramps.instructure.com/courses/3820435/quizzes/10614998 1/13

3/7/24, 9:01 PM 4.1.1.1 Introduction to Momentum: Mechanics, Heat, & Sound - HS - Wilkes, Deborah Half of it goes to the 8-ball, and half stays with the cue ball. Question 2 1/1 pts A bulldozer and a Mini Cooper are involved in a head-on collision. Which one experiences a greater force? Which one has a greater impulse? Which one has a greater change in velocity? They experience equal forces and impulse. They have the same change in velocity. Correct! They experience equal forces and impulse. The Mini Cooper would have the greater change in velocity. The Mini Cooper experiences greater force and impulse. The Mini Cooper would have the greater change in velocity. The bulldozer experiences greater force and impulse. The bulldozer would have the greater change in velocity. They experience equal forces and impulse. The bulldozer would have the greater change in velocity. Question 3 1/1 pts An astronaut went out for a spacewalk and became stranded some distance away from her space station. All she has with her is her bag of tool. How can she get back to the space station? Explain your answer. Your Answer: She should throw the tools in the opposite direction of the station to get back to the station. Question 4 0/1pts Objects on Mars weigh about 38% what they do on Earth. While driving on Earth, a Mars rover moves at a speed of 30 mph. If the rover moves with the same speed on Mars, would it have more, less, or the same momentum as when on Earth? Correct Answer Same momentum You Answered Less momentum More momentum More information needed https://onramps.instructure.com/courses/3820435/quizzes/10614998 2/13

3/7/24, 9:01 PM 4.1.1.1 Introduction to Momentum: Mechanics, Heat, & Sound - HS - Wilkes, Deborah Question 5 1/1 pts Explain why it feels more forceful when you catch a baseball with your bare hand, as opposed to catching it with a glove. Your Answer: The energy of the ball is transfer to the glove and hand so the hand take less energy because the glove also takes energy from the ball. Compared to when you catch the ball bare handed because your hand takes all the energy. Question 6 1/1 pts Suppose a student throws a pencil at the wall, and upon hitting the wall, the pencil breaks in half. What happens to the original momentum of the pencil? Your Answer: The wall takes all the energy than gives it back to the pencil and than energy breaks the pencil. Question 7 1/1 pts If you throw a ball horizontally while standing on roller skates, you roll backwards. Will you roll backwards if you go through the motions of throwing the ball, but hold on to it instead? Yes Correct! No More information needed Question 8 1/1 pts When an apple falls from a tree and strikes the ground without bouncing, what becomes of the momentum? Your Answer: The energy is transferred to the earth. Sketch the results you expect for each of the following collisions. Explain your reasoning for each. For each situation use velocity vectors over each cart to indicate how much velocity each cart has. https://onramps.instructure.com/courses/3820435/quizzes/10614998 3/13
