Homework Statement
A 700 g air-track glider collides with a spring at one end of the track. The figure shows the glider's velocity and the force exerted on the glider by the spring.
How long is the glider in contact with the spring?
Homework Equations
F(t_1-t_2)=mv_2-mv_1
The Attempt at a Solution
I have the force as 36N, v_1 as -3, v_2 as 3.
When I plug this into the equation I get
change in t = (700*3-700*(-3))/36=116.6
I know this has to be wrong but I'm confused which variable I have wrong. Maybe the force?
