A uniform plank of length 4.7m and weight 204 n rests, Ask an Expert

Academics

Q. A spring with spring constant 18.5 N/m hangs from the ceiling. A 440 g ball is attached to the spring and allowed to come to rest. It is then pulled down 6.00 cm and released.

What is the time constant if the ball's amplitude has decreased to 2.30 cm after 55.0 oscillations?

Q. A uniform plank of length 4.7 m and weight 204 N rests horizontally on two supports, with 1.1 m of the plank hanging over the right support. To what distance x can a person who weighs 445 N walk on the overhanging part of the plank before it just begins to tip?
