You pull a solid copper ball with a density of 8.92 g/cm3 and a radius of 1.50 cm upward through a fluid at a constant speed of 6.00 cm/s. The fluid exerts a drag force that is directly proportional to speed, and the proportionality constant is 0.950 kg/s. What is the magnitude of the force (in N) you exert on the ball? (You may ignore the buoyant force.) Answer:__________N What If? By what percentage would the upward force exerted on the copper ball have to be increased for the speed of the ball in the fluid to increase to quadruple its original value?
