Q. A uniform plank of length 5.0 m and weight 231 N rests horizontally on two supports, with d = 1.43 m of the plank hanging over the right support. To what distance, x, can a person who weighs 446 N walk on the overhanging part of the plank before it just begins to tip?

Q. A 48 kg pole vaulter running at 12 m/s vaults over the bar. Her speed when she is above the bar is 0.7 m/s. Neglect air resistance, as well as any energy absorbed by the pole, and determine her altitude as she crosses the bar.
