Questions 11-13 refer to a coin which is tossed straight up into the air. After it is released it moves upward, reaches its highest point and falls back down again. Use one of the following choices (A through G) to indicate the force acting on the coin for each of the cases described below. Answer choice J if you think that none is correct. Ignore any effects of air resistance. A.  The force is down and constant.B.  The force is down and increasing.C.  The force is down and decreasing.D.  The force is zero.E.  The force is up and constant.F.  The force is up and increasing.G.  The force is up and decreasing. Question 13: The coin is moving downward.

Questions 22-26 refer to a toy car which can move to the right or left on a horizontal surface along a straight line (the + distance axis). The positive direction is to the right. Different motions of the car are described below. Choose the letter (A to G) of the acceleration-time graph which corresponds to the motion of the car described in each statement. You may use a choice more than once or not at all. If you think that none is correct, answer choice J. Question 23: The car moves toward the right, slowing down at a steady rate.

Questions 27-29 refer to a coin that is tossed straight up into the air. After it is released it moves upward, reaches its highest point and falls back down again. Use one of the following choices (A through G) to indicate the acceleration of the coin during each of the stages of the coin’s motion described below. Take up to be the positive direction. Answer choice J if you think that none is correct. A.  The acceleration is in the negative direction and constant.B.  The acceleration is in the negative direction and increasing.C.  The acceleartion is in the negative direction and decreasing.D.  The acceleration is zero.E.  The acceleration is in the positive direction and constant.F.  The acceleration is in the positive direction and increasing.G.  The acceleration is in the positive direction and decreasing. Question 27: The coin is moving upward after it is released.
