A thin rod of length 0.75 m and mass 0.42 kg is suspended
freely from one end. It is pulled to one side and then allowed to swing
like a pendulum, passing through its lowest position with angular
speed 4.0 rad/s. Neglecting friction and air resistance, find (a) the
rod's kinetic energy at its lowest position and (b) how far above that
position the center of mass rises.

The rocket is fired vertically and tracked by the radar station shown. when ΞΈ reaches 66Β°, other corresponding measurements give the values r = 32700 ft, rΒ¨ = 85 ft/sec2, and ΞΈΛ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.
