Question

A 0.50-kg glider is moving to the right with a speed of 0.8 m/s on a frictionless horizontal air track. The glider has a head-on collision with a 0.70-kg glider that is moving to the left with a speed of 1.5 m/s. if the collision is completely inelastic (they stick together):

1. what is the final speed of gliders?

2. In what direction the glider will go? (left or right)

3.How much energy is lost in the system during the collision?

Answer #1
