If anyone could help me with my homework I would GREATLY appreciate it. I am totally lost. There are 2 questions. If you could tell me what/how to do it, I'd be happy to do it. I just need to know how. Thanks so much

Here is part 1:

A .102 kg block sliding on a frictionless surface with initial velocity of .70 m/s slams into a spring at a horizontal coordinate Xo = 0. The spring brings the block to a stop (v=0) at some coordinate X. Use the conservation of mechanical energy to find the stopping distance.

note: since the spring resists with force F=kx the potential energy is Ep=Fx x=kx^2 where k is called the force constant we'll use k = 4.45 N/m

Given:

m=.102 kg

Vo=.70 m/s

Xo=0

k=4.45 N/m

v=0
