3. How does Newton’s Second Law of Motion describe the motion of the pendulum bob when it is released?

4. How does Newton’s Third Law of Motion (For every force there is an equal and opposite reaction force) help to describe the motionless pendulum bob as it sits now?

5. If gravity accomplishes 12 J of work on the pendulum bob with 10 N of force, how far will the bob travel?

6. If the bob travels 2 meters at a speed of 3 meters per second, how much time went by?
