Homework Statement
Two carts have a spring of negligible mass compressed between them. The spring has a force constant of 8000 N/m and is compressed 0.05 m from equilibrium. Cart 1 has a mass of 1.3 kg and cart 2 has a mass of 0.5 kg.
What is the speed of cart 1?
What is the speed of cart 2?
Homework Equations
p=mv
F=ma
U=(.5)kx^2
K=(.5)mv^2
F=kx
The Attempt at a Solution
F=kx
F=400
400 = (.5)m1v1^2 + (.5)kx^2
800 = m1v1^2 + kx^2
780 = m1v1^2
v1 = 24.494 m/s
but it's wrong.. anyone can help me?
