Need help with a spring question

A 60.5 kg woman is running at a 15.0 kg sled at a speed of 11.9 m/s. After she jumps on the sled, she travels down a 54.0 m long hill that is at an angle of 25.9 and the spring at the bottom compresses by 3.30 m. What is the spring constant of the spring?

I'm not sure where to start with this question if someone could help me out that would be great. Thanks!

Remember that there are always multiple ways to investigate a problem. In this case, it helps to see things in terms of energy instead of just motion and forces.

Have a go of these mini questions:

1. When the woman is running, what kind of energy does she have?
2. Can you calculate how much energy?
3. When the woman is sliding down the hill, what happens in terms of energy?
4. How much energy is converted?
5. When the woman ends up on the spring, what happens in terms of energy?
6. How much energy is converted?
