PART 1: A small ball of mass 0.5 kg is attached to one end of a 1.8-m-long massless rod, and the other end of
the rod is hung from a pivot. When the resulting pendulum is 40° from the vertical, what is the magnitude of the
gravitational torque calculated about the pivot? 
PART 2: What are the magnitudes of (a) the angular velocity, (b) the radial acceleration, and (c) the tangential
acceleration of a spaceship taking a circular turn of radius 3500 km at a speed of 27 000 km/h?
