Question

1.20kg mass is dropped from a height of 0.9M unto a spring with force constant K= 120N/m and negligible mass. Find the maximum distance the spring will compressed

pls show full working and indicate formular.

Answer 1

At maximum compression X, the spring's potential energy will equal the gravitational potential energy loss.

M g (H +X) = (k/2)*X^2

Solve for X
