[Free] 1. An 8-kilogram bowling ball is rolling in a straight line toward you. If its momentum is 16 kg·m/s, how fast is it traveling? 2. A beach ball is rolling in a straight line toward you at a speed of 0.5 m/s. Its momentum is 0.25 kg·m/s. What is the mass of the beach ball? 3. A 4,000-kilogram truck travels in a straight line at 10.0 m/s. What is its momentum? \[ \text{Momentum} = \text{mass} \times \text{speed} = 4,000 \times 10 = 40,000 \text{ kg·m/s} \] 4. A 1,400-kilogram car is also traveling in a straight line. Its momentum is equal to that of the truck in the previous question. What is the velocity of the car? 5. Which would take more force to stop in 10 seconds: an 8.0-kilogram ball rolling in a straight line at a speed of 0.2 m/s or a 4.0-kilogram ball rolling along the same path at a speed of 1.0 m/s? 6.
