A meter stick with a mass of 0.166kg is pivoted about one end so itcan rotate without friction about horizontal axis. The meter stickis held in a horizontal position and released. As it swings throughthe vertical, calculate:
a) change in gravitational potential energy that hasoccurred;
b) the angular speed of the stick;
c) the linear speed of the end of the stick opposite theaxis.
d) Find the ratio of the speed of a particle that has fallen adistance of 1.00 m, starting from rest, to the speed from part (C).
