Graph of Velocity vs. Time of a glider on an air track?

Question

What would the graph of veloicty vs. time look like for a glider on a level air track? I appreciate your time and insight in this manner. God Bless

Answer 1

How is the glider configured?

Usually these devices are configured with a cord over a pulley to a weight that is suspended.

The glider has mass m1 and the suspended weight has mass m2. Friction is negligible on the air track and the pulley is usually considered mass less, so

The tension in the cord is T
T=m2*g
and
T=m1*a

Where a is the acceleration of the glider
a=m2*g/m1

Using the equation of motion for velocity in a constant acceleration and zero starting velocity:
v(t)=t*m2*g/m1
