If the moremassive player experiences a -3.50 m/s2 acceleration, what acceleration does the lessmassive player experience after the collision? Use following information to answer parts a–c: Jack has a dream that he is stranded in the middle of a frozenpond. The ice is frictionless so he isn’t able to walk or push off ofthe ice to get back to shore. All he has is his backpack carrying hisheavy physics textbook. a) Identify a pair of action and reaction forces that Jack could use to get back toshore. b) Explain how Jack could minimize the amount of time it takes for him to get toshore (consider Newton’s Second Law). c) Compare and contrast a rocket launch with Jack’s strategy to get back to shore.Use the principles of Newton’s Third Law in your answer.
1)A person jumps from a wall and lands stiff-legged. Which statement best explains why the person is less likely to be injured when landing on soft sand than on concrete? Select all that apply. a. The upward acceleration of the person in the sand is less than on concrete, thus the force that the sand exerts on the person is less. b. The person sinks into the sand, increasing the stopping distance. c. The concrete can exert a greater force than the sand. 2)You are inside a car that is speeding up, and you notice a book on the seat next to you starting to slide back. What is happening? a. Not enough information is given to answer the question. b. The sum of the forces on the book is 0, but is looks like it still accelerating because Newton's 2nd Law doesn't apply in this situation. c. The seat is exerting a horizontal force on the book pointing backwards.. 3)A person pushes a 8 kg crate, exerting a 64 N force on it, but the crate’s acceleration is only 5 m/s2.…
