Student : ___________________ Impulse & Momentum Section:______ Date:__________ 1. Find the impulse on a box that is pushed with 150N for 2.5s. 2. You push a chair. If you push it again with less force could you get it to go just as fast? How? 3. With impulse, force and time have an inverse relationship. This means that increasing the amount of time used will need ________________(more/less) force to accomplish the same task. 4. Given the following data, solve for momentum, or mass, or velocity Object Bird Football player Skier Bullet Frog Meteorite Baseball Wagon Satellite Mass (kg) .04 1000 80 .9 .1 Velocity (m/s) -5 Momentum (kg-m/s) 1000 10 700 2.4 10.8 1,000 40 9 4.2 6 24000000 2,000 Student : ___________________ Impulse & Momentum Section:______ Date:__________ 1.

List the object from least to greatest momentum 6. Do you think that these objects would always be placed in the same order according to momentum? Why or why not? 7. Momentum is a _______________(vector /scalar) quantity. 8. A locomotive has a mass of 200,000 Kg. It is moving at 4.5 m/s. How fast would a car (mass 1000Kg) be traveling to have the same momentum? 9. A red car is traveling 15m/s to the east while an identical yellow car is traveling 15m/s to the west. Do they have the same momentum? (Hint: does direction matter?) 10. Which ball is harder to stop and why? A bowling ball or a tennis ball. Both have the same velocity. 5.
