Speeding up Slowing down Submit Request Answer Provide Feedback Next >

Based on the information provided, block B is speeding up once it is set into downward motion and the cat is on block A. This is because block B descends at a constant speed, indicating that the forces acting on it are balanced. Since block A is connected to block B via the pulley, and the mass and friction of the pulley are negligible, the force exerted by the cat on block A is equal and opposite to the force exerted by block B on the pulley. Therefore, block B is accelerating downward, which means it is speeding up.
