Question

A meter stick with a mass of 0.155 kg is pivoted about one end so it can rotate without friction about a horizontal axis. The meter stick is held in a horizontal position and released. As it swings through the vertical, calculate:
a. change in gravitational potential energy that has occurred;
b. the angular speed of the stick;
c. the linear speed of the end of the stick opposite the axis.
d. Compare the answer in part (c) to the speed of a particle that has fallen 1.00m, starting from rest.

Answer 1

Answer: a) P.E = - 0.76J

b) W = 2.7 rad/s

c) V = 2.7m/a

d) V = 4.43 m/s
