A stick with a mass of m and a length of L 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.
Part A) As it swings through the vertical, determine the change in gravitational potential energy that has occurred. Use g for the acceleration due to gravity.
Part B) As it swings through the vertical, estimate the angular speed of the stick.
Part C) As it swings through the vertical, estimate the linear speed of the end of the stick opposite the axis.
Part D) Calculate the ratio of the speed of a particle that has fallen a distance of L, starting from rest, to the speed from part(C).
