A 5 kg mass is thrown up with a velocity of 4 m/s from a height of 30 m onto a spring with a relaxed length of 10 m, and a constant of 400 N/m. What will the maximum compression of the spring be? What will the speed of the object be when the spring is compressed 0.3 m?

This looks like a duplicate post. I amswered it already
I think you have this question confused with this one:
A 200 N/m, 5 m spring on a 20 degree incline is compressed 2.3 m and a 5 kg block is placed on it. If we neglect friction, how far up the incline will the block travel? How fast will it be traveling when it is 0.2 m up the incline?
