A 1.5 kg crate falls from a height of 2.0 m onto an industrial spring scale with a spring constant of 1.5 *10⁵ N/m. At its greatest compression the reading on the scale is:

Question

Quizplus · Accepted Answer

The potential energy of the crate is converted into the elastic potential energy of the spring. Using the conservation of energy, mgh = 0.5kx^2, and solving for the force (kx) gives the reading on the scale.
