... axle. It is initially stationary. A torque of 100 N m is applied to the axle for 100 s. (i) Calculate the final angular velocity of the flywheel. v = u + at = u + F/m t, so f = I + t = 0 + /I t = 2000 rads–1. (ii) Calculate the final angular momentum of the flywheel. L = If = 5 2000 = 10000 k ...

... On Earth, a baseball player can hit a ball 120 m by giving it an initial angle of 45° to the horizontal. Take the acceleration due to gravity as g = 10 m/s2. Suppose the batter repeats this exercise in a space “habitat” that has the form of a circular cylinder of radius R = 10 km and has an angular ...
