Homework Statement
A block of mass 20.0 kg slides without friction at a speed of 6.0 m/s on a horizontal table surface until it strikes and sticks to a mass of 5.o kg attached to a horizontal spring (with a spring constant of k=8000.00 N), which in turn is attached to a wall. How far is the spring compressed before the masses come to rest?
Homework Equations
Kf-Ki = W
W = 1/2Kx^2
The Attempt at a Solution
Ki = 1/2(20kg)(6.0m/s)^2 = 360
I'm not sure how to account for the collision between the 20kg mass and the 5kg mass.
