1. Calculate the momentum of a 4.0 kg object traveling 6. A 7.0 kg object travels 2.6 m west in 1.1 s. Assuming at a velocity of 12.0 m/s east. uniform velocity, what is the momentum of the object? 2. A 5.0 kg object has a momentum of 25.0 kgm/s west. 7. A 5.0 kg object is dropped from a height of 2.5 m What is its velocity? above the floor. What is the object's momentum after 0.25 s? 8. A 1.0 kg ball hits the floor with a velocity of 2.0 m/s. 3. An object has a velocity of 8.0 m/s south and a If the ball bounces up with a velocity of 1.6 m/s, what is momentum of 36.0 kgm/s south. What is its mass? the ball's change in momentum? 4. An object has a velocity of 2.0 m/s east and a 9. A 0.144 kg baseball is pitched horizontally at + 38 momentum of 29 kgm/s. What is the weight of the m/s. The batter hits a horizontal line drive at - 38 m/s object? (the opposite direction!). What is the ball's change in momentum? 5. A 6.6 N object is traveling at a velocity of 3.0 m/s north. What is the object's momentum? 10. The 1205 kg physics dragster is traveling at 35 km/h east when it hits the gas and accelerates at 12.5 m/s2 for 3.25 s. What is its change in momentum during this time
