 Homework Statement:

A small cube, with a mass of 25 g, slides along a frictionless horizontal surface at a constant speed of 18 m/s until it collides with, and sticks to, a large wooden 3.5 kg block. The large block is attached to the left end of a spring with a spring constant of 100 N/m as shown above.
a. What is the momentum of the cube before the collision?
b. What is the kinetic energy of the cube before the collision?
c. *Find the speed of the combined cube and block system just after the collision.
d. *Find the kinetic energy of the cubeblock system just after the collision.
e. *What is the maximum potential energy that can be stored in the spring due to this collision?
f. *How far will the cubeblock system move before it stops?
 Relevant Equations:

KE = 1/2 mv^2
P= mv
maybe D = (KE) / (m)(g) ?
So far I found the answer for a and b, but when I attempted to do the other ones I was completely lost.
A.) P= MV
M = 25g = .025kg
V = 18
.025 * 18 = .45kg*m/s
B.) KE= 1/2 mv^2
1/2 (.025)(18)^2
4.05 J
