Question

A 0.07 kg toy is made up of a spring of constant 375 N/m. When you place the toy on the floor, cock the spring 7 cm and release it, the toy jumps upwards. What is in Joules the mechanical energy of the toy when sitting on the floor with a cocked spring? Use 10 m/s2 for g.

Answer 1

I can't figure out what the censored word is, and its meaning in the problem.
One needs to know how much the spring is compressed.
