Q1. Consider a too-small space station that consists of a 4 m radius rotating sphere. A man standing inside is 2m tall and his feet are at 1g. What is the acceleration of his head?

Q2. An electric motor rotating a workshop grinding wheel at a rate of 1.02 x 10^2 rev/min is switched off. Suppose the wheel has a constant negative angular acceleration of magnitude 1.50 rad/s2.

Q3. A 3.60 long, 420 steel beams extends horizontally from the point where it has been bolted to the framework of the new building under construction. A 72.0 construction worker stands at the far end of the beam. What is the magnitude of torque about the point where the beam is bolted into place?
