Where he should aim does not depend on the velocity of the plane. E. Not covered in the assigned reading. Bullet G is dropped, from rest, at the same time that another bullet H is fired horizontally from a rifle. Assume that the earth is flat. If both bullets leave from the same height above the ground, then A. bullet G hits the ground before bullet H does. B. both bullets hit the ground at the same time. C. bullet H hits the ground before bullet G does. D. not enough information is given to compare when they hit. E. Not covered in the assigned reading. 9. 10. A marble flying through the air is moving sideways at 3 m/s at the same time it is moving downward at 4 m/s.

Can an object's velocity change direction when its acceleration is constant? A. No, this is not possible because it is always speeding up. B. No, this is not possible because it is always speeding up or always slowing down, but it can never turn around. C. Yes, this is possible, and a rock thrown straight up is an example. D. Yes, this is possible, and a car that starts from rest, speeds up, slows to a stop, and then backs up is an example. E. Not covered in the assigned reading Suppose that an object is moving with constant acceleration. is an accurate statement concerning its motion? A. In equal times its speed increases by equal amounts. B. In equal times its velocity changes by equal amounts. C. In equal times it moves equal distances. D. None of these are true. E.
