Q2 An object is moving in the +y direction. Which, if any, of the following statements might be true? Check all that apply. (a) The net force on the object is zero. (b) The net force on the object is in the -y direction. (c) The net force on the object is in the +y direction. Q3 You observe three carts moving to the left. Cart A moves to the left at nearly constant speed. Cart B moves to the left, gradually speeding up. Cart C moves to the left, gradually slowing down. Which cart or carts, if any, experience a net force to the left? Q4 In order to pull a sled across a level field at constant velocity you have to exert a constant force. Doesn't this violate Newton's first and second laws of motion, which imply that no force is required to maintain a constant velocity? Explain this seeming contradiction.
