2. Analysis of Pendulum Motion a) The simple pendulum shown has a mass of 45g attached to a thread with length L = 0.5 m. It is initially at rest, and released from the position shown in the figure below at right at an initial angular displacement 0₁ = 30°. What is the maximal speed Vmax of the mass at the bottom of the arc shown? What is the maximum height hf the mass achieves? What is the maximal speed the mass will achieve coming back down from its maximal height? For all of the previous questions, assume that the frictional drag force is negligible. v₁ = 0 L V₁=0 y=h, --y=0

2. Analysis of Pendulum Motion
a) The simple pendulum shown has a mass of 45g attached to a thread with length L = 0.5 m. It is
initially at rest, and released from the position shown in the figure below at right at an initial
angular displacement 0₁ = 30°. What is the maximal speed Vmax of the mass at the bottom of
the arc shown? What is the maximum height hf the mass achieves? What is the maximal speed
the mass will achieve coming back down from its maximal height? For all of the previous
questions, assume that the frictional drag force is negligible.
