Homework Statement
A 2kg cart has a spring with k=5000N/m attached to its
front parallel to the ground. This cart rolls at 4m/s toward a stationary
1kg cart.
What is the maximum compression of the spring during the collision
The Attempt at a Solution
I think the spring will stop compressing when the 2 carts are moving
at the same speed. And there will be a point where the potential energy in the spring
plus the KE of the 2 carts will equal the original energy of moving cart.
so I think I should start with
[itex] kx^2+m_2v^2+m_1v^2=m_2{v_0}^2 [/itex]
now I need another equation because I have 2 unknowns in my one equation
