Physic Problem: Work and Spring

A 0.239 kg shoe is dropped onto a vertically oriented spring with a spring constant of 103 N/m. The shoe becomes attached to the spring upon contact, and the spring is compressed 0.115 m before coming momentarily to rest.
What work is performed by the weight of the shoe while the spring is being compressed? 0.270J]
What work is done by the spring force? 0.681J

Please help with followings:

1. At what speed is the shoe traveling just before it hits the spring?

2. If the speed of the shoe just before impact is doubled, what is the maximum compression achieved by the spring?

It would be great if you could show me how to solve this step-by-step along with its final answer.

Thank you so much!
