Answer:
The spring constant of the spring is .
Explanation:
Mass of the rock is 2.5 kg
It is dropped off a 32 m cliff and hits a spring, compressing it 57 cm. It is required to find the spring constant.
When it falls form a height, it possess potential energy and when it hits a spring, the potential energy gets converted to elastic potential energy such that :
Here, k is spring constant
So, the spring constant of the spring is .
