Only number 3 A and B

3. The Velcro is removed from the gliders, so the gliders bounce apart after the collision. The initial velocities are the
same but now the 3 kg glider moves at 1.5 m/s to the left after the collision.
a. What was the final velocity of the 2 kg glider after the collision? Give speed and direction.
b. How much kinetic energy was lost during the collision?

2. Two gliders are on a very long air track with negligible friction. The 3 kg glider is initially located 2 meters from the
left end of the track and moving at 2 m/s to the right. The 2 kg glider is initially 5 meters from the left end and is
moving 6 m/s to the left. There are springs with k = 50 N/m at each end of the track.

2 kg
a. Where is the center of mass of the two-glider system initially located, measured from the left end of the track?
b. The gliders are equipped with Velcro so they stick together after colliding, what will be their speed and direction
(left/right) after the collision?
c. The gliders eventually hit a spring. What is the maximum distance the gliders compress the spring?
