1. An object is moving to the right with speed v when a force of magnitude F is exerted on it. In which of the following situations is the object's direction of motion changing and kinetic energy decreasing at the instant shown? (A) Original answer B Correct answer D Justification: FLDE ٧٠ Fsm mg (C) Since Fsm is in the opposite direction as V; then velocity is going to decrease and Smee KE=m² Kinetic energy is going to decrease, and since Foos is pulling the object into an upward motion the object is going to charge motion.
