HW29#7 – An 8.00 kg stone resting on a spring. The spring is compressed 20.0 cm by the stone. What is the spring constant?

歡迎來到Yogi老師解題給你看,今天我要講解的是AP Physics C Mechanics的問題

The figure shows an 8.00 kg stone resting on a spring. The spring is compressed 20.0 cm by the stone.

a)What is the spring constant?

b)The stone is pushed down an additional 30.0 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?
