What is the momentum of a 5000. kg Asian elephant running 6.80 m/s? 5000x6.80=34000 2. What is the momentum of a 13.0 g bullet traveling at 1200. m/s? 3. If the bullet in problem 2 comes to rest in a wooden block, what is the change in momentum of the bullet? 4. If the block in problem 3 stops the bullet in .015 s, what is the average force that the block places on the bullet? Consider the graph below that depicts the force applied to an object as a function of time. 5. What is the impulse delivered to the object from 0.00 s to 18.0 s? 6. Suppose the mass of the object in the figure is 10.0 kg, and the object was at rest at t = 0.00s. What is the object’s velocity at 10.0 s? 7. A railroad car of mass 8.0 x 10 4 kg is traveling along a straight track when it couples with a second car of mass 9.0 x 10 4 kg initially at rest. a.
