Elastic and Plastic Behaviour

Elastic and Plastic Behaviour problem 17

A spiral spring with elastic constant is compressed by 1.0 cm.

  • How much work is done when compressing the spring?

  • By how much, at least, must the spring be compressed in order for it to shoot a 100 g mass to a vertical height of 3.0 m when released?

    Neglect air resistance, and also the change in potential energy during the stretching of the spring.
