1. The problem statement, all variables and given/known data A spring with an elastic constant of 120 N/m is compressed 0.2 m, then launches a block of mass 0.5 kg on a table with friction 0.49, and it travels 0.9 m before stopping. If the block is then released at the edge of a table top 1.2 m above the ground, how far will the block travel? 2. Relevant equations F = 1/2KX2 Vf2 - Vi2 = 2a(delta x) Vf2 - Vi2 = -2g(delta y) 3. The attempt at a solution I am stumped. I think these equations are relevant, but I'm not totally sure. I already solved for the friction coefficient, so some of those numbers may now be unimportant.
