suppose the glider is initially at rest at x=0, with the spring unstretched. You then apply a constant force in the +x direction with magnitude 0.610 N to the glider. what is the glider's velocity when it has moved 0.100m?

Answer 1

I think you left out the mass m of the glider.

With acceleration a, after distance s, the velocity v is:

v = √(2as) = √(2 * 0.610/m * 0.100) = √(12.2/m)
