| An ostrich with a mass of 146 kg is running to the right with a velocity of 17 m/s. Find the momentum of the ostrich. | ??? |
| A 21-kg child is riding a 5.9-kg bike with a velocity of 4.5 m/s to the northwest. What is the momentum of the child? the momentum of the bike? the momentum of the child and bike together? | ??? |
| A 2250-kg pickup truck has a velocity of 25 m/s to the east. What velocity must a car with a mass of 1210 kg have in order to have the same momentum? | ??? |
| A 1400-kg car moving westward with a velocity of 15 m/s collides with a utility pole and is brought to rest in 0.30 s. Find the magnitude of the force exerted on the car during the collision. | ??? |
| A 0.40-kg soccer ball approaches a player horizontally with a velocity of 18 m/s to the north. The player strikes the ball and causes it to move in the opposite direction with a velocity of 22 m/s. What impulse was delivered to the ball by the player? | ??? |
| A 0.50-kg object is at rest. A 3.00-N force to the right acts on the object during a time interval of 1.50 s. What is the velocity of the object at the end of this time interval? | ??? |
| A 2250-kg car traveling to the west slows down uniformly from 20.0 m/s to 5.00 m/s. How long does it take the car to decelerate if the force on the car is 8450 N to the east? | ??? |
| A 76-kg boater, initially at rest in a stationary 45-kg boat, steps out of the boat and onto the dock. If the boater moves out of the boat with a velocity of 2.5 m/s to the right, what is the final velocity of the boat? | ??? |
