Will mark the brainliest A 4.0kg ball is thrown vertically up into the air with an initial velocity of 8.5ms −1. By the time it is height h metres above the starting point, it has a velocity of 3.0ms −1 and has done 4.0J of work against air resistance. Find h.

The space between two 15-in.-long concentric cylinders is filled with glycerin (viscosity = 8.5 × 10-3 lb·s/ft2). the inner cylinder has a radius of 1 in. and the gap width between cylinders is 0.1 in. determine (a) the torque and (b) the power required to rotate the inner cylinder at 180 rev/min. the outer cylinder is fixed. assume the velocity distribution in the gap to be linear.
