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.

The figure shows a pellet about to be fired from a sling. The total unstretched length of the rubber band is 80mm. The rubber band elongates 1mm for every 15N force.Given: a=100mm b=40mm
1. As the pellet is about to be released, how much is the elongation on each leg (mm) of the rubber band?
2. What is the force (N) exerted on each leg of the rubber band?
3. What is the pulling force (N)?
A vertical rectangular object of uniform mass M = 8 kg has sides a = 0,21 m and
b = 0,67 m. It is pivoted from point O as shown in the figure below. If a constant force of
F = 118 N along the diagonal is applied as shown below, determine the angular acceleration
of the rectangle in SI units at the instant shown. Express your answer using one decimal place.
Please use the convention: Clockwise (+), Counterclockwise (-) when expressing your answer.
Hint 1: The moment of inertia of a uniform disk about an axis of rotation passing through the
center of mass (CM) is ICM = M(a² + b²).
Hint 2: Don't forget the force of gravity!!! Take g = 9.80 m/s².
