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

Work equal to F*X = 0.061 Joules will have been performed on the glider.

You need to knmow the glider's mass, and what the spring is doing, to calculate the glider's velocity.
