Description
The figure shows an 8.3 kg stone at rest on a spring. The spring is compressed 9.9 cm by the stone. (a) What is the spring constant? (b) The stone is pushed down an additional 31 cm and released.What is the elastic potential energy of the compressed spring just before that release? (c) What is the change in the gravitational potential energy of the stone–Earth system when the stone moves from the release point to its maximum height? (d) What is that maximum height, measured from the release point?
Tarzan, who weighs 652 N, swings from a cliff at the end of a convenient vine that is 13 m long (see the figure). From the top of the cliff to the bottom of the swing, he descends by 3.0 m. The vine will break if the force on it exceeds 1150 N. What would the greatest force on the vine be during the swing?
I will post the original questions down below with pictures.
