Chapter 17, Problem 11Q(choose chapter or problem)
A pendulum is launched from a point that is a height above its lowest point in two different ways (Fig. 6-32). During both launches, the pendulum is given an initial speed of
On the first launch, the initial velocity of the pendulum is directed upward along the trajectory, and on the second launch it is directed downward along the trajectory. Which launch will cause it to swing the largest angle from the equilibrium position? Explain.

ANSWER:
Step 1 of 2
The kinetic energy at the lowest point for a simple pendulum changes to the potential energy at the top position.
The kinetic energy at the lowest is,
