Calculate the force required to pull a copper ball of mass 0.3 kg upward through a fluid at the constant speed 9.00 cm/s. Take the drag force to be proportional to the speed, with proportionality constant 0.950 kg/s. Ignore the buoyant force.

Step 1
The weight is given by the formula F_gravity = m * g, where m is the mass and g is the acceleration due to gravity. With m = 0.3 kg and g ≈ 9.80 m/s², we have: F_gravity = 0.3 kg * 9.80 m/s² = 2.94 N. Show more…

(a) 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 8.00 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.) (In N) (b) 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?

A ball is held submerged in a bucket of water by a string attached to the bucket's bottom. Water density is 1000 kg/m^3. The ball has a mass of 0.5 kg and a volume of 0.006 m^3. What is the buoyant force on the ball? What is the tension force on the ball?
