Physics 30: Module 1: Lesson 1 3 Assignment Module 1: Lesson 1 ASSIGNMENT This Module 1: Lesson 1 Assignment is worth 26 marks. The value of each assignment and each question is stated in the left margin. (26 Marks) Lesson 1 Assignment: Momentum and Newton’s Second Law (4 marks) TR 3. Use reasoning to determine if one of the following objects in each of these pairs has a greater value for the magnitude of its momentum than the other. (No calculations should be required.) a 900.0-kg truck travelling at 60 km/hr, or a 500.0-kg car travelling at 60 km/hr Answer: a 15.0-kg object travelling to the right at 5.0 m/s, or a 15.0-kg object travelling to the left at 5.0 m/s Answer: a 900-kg truck at rest, or a 500-kg car at rest Answer: a 900-kg truck at rest, or a mosquito flying at 2 m/s Answer: (5 marks) TR 4. Solve question 9 on page 453 of your textbook. Answer: 9. (5 marks) TR 5. Solve question 12 on page 453 of your textbook. Answer: 12. (5 marks) TR 6. Solve question 15 on page 453 or your textbook. Answer: 15. In the discussion forum, use the concepts of momentum and Newton’s second law to explain why the following statements are true. (1 mark) D 1. A large freight train moving down the tracks takes a long time to stop. Answer: (1 mark) D 2. A motorcycle can have the same momentum as a large truck. Answer: (1 mark) D 3. In general, a motorcycle can accelerate at a greater rate than a large truck. Answer: (4 marks) Reflect on the Big Picture In real life, a police officer may warn that “speed kills.” In video games, high-speed crashes are common. Suppose a particular scene in a game required the following elements: A high performance motorcycle must crash into a barrier and be stopped. A small scooter must crash into another section of the same barrier and be stopped. The forces exerted as each vehicle collides with the barrier change the shape of that section of the barrier in addition to stopping the vehicle. The time required to stop each vehicle must be realistic. Create a paragraph, illustration, animation, or audio recording to explain how you could use the concept of momentum and net force to make each simulated crash realistic. In general, how could you use momentum and Newton's laws of motion to predict the amount that each section of the barrier changes shape? Store your completed reflection in your Physics 30 course folder, and submit your creation to your instructor for marking. Answer: Once you have completed all of the questions, submit your work to your teacher.
