Please Help! (Momentum I Think)
Could someone help me with this problem? I'd greatly appreciate it!
A block of mass M = 1.00 kg contains a coiled spring and a ball of mass m = 0.250 kg.
The spring is released when the block-ball system is at rest on the edge of a frictionless
plane inclined 20 degrees from the horizontal. The ball, initially 2.00 m above the horizontal
floor, strikes the floor a horizontal distance of 3.00 m from the release point. How far
along the plane does the block move? How much energy was initially stored within the
spring?

I've tried summing forces, conservation of enrgy, conservation of momentum, and I can't work it out. Any little hint helps! Thanks!
