A glider (Glider #1) has a mass of 18.7 gg and is initially moving at a speed of 23.1 cm/s on a horizontal air track. It then strikes a glider (Glider #2) of mass 39.6 g that is initially at rest. If the collision is perfectly elastic, what is the velocity of Glider #1 after the collision? Express the answer in cm/s. Note: Consider the initial direction of Glider #1 as being the direction of positive velocity.
