Question 9
This question contains multiple parts. Make sure to read all the instructions and answer each part.
spherical beach-ball of radius 20cm and average density 3kg/m³ is pushed downward under water at a constant speed of 1.62m/s to a depth of 2.21m below its starting point near the surface.
ou may assume that the ball remains submerged the whole time, that it moves in the high Reynolds number regime with quadratic drag and that its drag coefficient is D≈ 0.5
