You pull a solid iron ball with a density of 7.86 g/cm^3 and a radius of 1.20 cm upward through a fluid at a constant speed of 7.00 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.)
