10. Can an automobile with a velocity toward the north simultaneously have an acceleration toward the south? 11. Light travels in a straight line at a constant speed of 300,000 km/s. What is the acceleration of light? 12. (a) Can an object be moving when its acceleration is zero? If so, give an example. (b) Can an object be accelerating when its speed is zero? If so, give an example. 13. If you drop an object, its acceleration toward the ground is 10 m/s2. If you throw is down instead, would its acceleration after throwing be greater than 10 m/s2? Why or why not?
