1.A bug and the windshield of a fast moving car collide. Tell whether the following statements are true or false:
1) The forces of impact on the bug and on the car are the same size. False
2) The impulses on the bug and on the car are the same size. False
3) The changes in speed of the bug and of the car are the same. False
4) The changes in momentum of the bug and of the car are the same size. True
2. Does a larger force always produce a larger impulse on an object than a smaller force? Explain.
3. A fully dressed person is at rest in the middle of a pond on perfectly frictionless ice and must go to shore. How can this be accomplished?
4. If 2 bodies collide and one is initially at rest, is it possible for both to be at rest after the collision? is it possible for one to be at rest after the collision? explain.
thanks!
