Question

A large truck collides head-on with a small compact car. During the collision: (A) the truck exerts a greater amount of force on the car than the car exerts on the truck. (B) the car exerts a greater amount of force on the truck than the truck exerts on the car. (C) neither exerts a force on the other, the car gets smashed simply because it gets in the way of the truck. (D) the truck exerts a force of the car but the car does not exert a force on the truck. (E) the truck exerts the same amount of force on the car as the car exerts on the truck. The accompanying figure shows a frictionless channel in the shape of a segment of a circle with center at "O". The channel has been anchored to a frictionless horizontal table top. You are looking down at the table. Forces exerted by the air are negligible. A ball is shot at high speed into the channel at "p" and exits at "r". Consider the following distinct forces: I. A downward force of gravity II. A force exerted by the channel pointing from q to O III. A force in the direction of motion IV. A force pointing from O to q Which of the above forces is (are) acting on the ball when it is within the frictionless channel at position q? (A) I only (B) I and II (C) I and III (D) I, II, and III (E) I, III, and IV Which path in the figure at right would the ball most closely follow after it exits the channel at "r" and moves across the frictionless table top?
