Two gliders move toward each other on a linear air track, which we assume is frictionless. glider a has a mass of 0.50 kg, and glider b has a mass of 0.30 kg; both gliders move with an initial speed of 2.0 m/s. after they collide, glider b moves away with a final velocity whose x component is +2.0 m/s. what is the final velocity of a? suppose glider b is initially moving to the left at 5.0 m/s when it runs into glider a, which is initially at rest. at what speed does glider a move away from the collision if glider b bounces back with a speed of 0.92 m/s?

-0.4 m/s

-3.552 m/s

Explanation:

= Mass of first glider = 0.5 kg

= Mass of second glider = 0.3 kg

= Initial Velocity of first glider = 2 m/s

= Initial Velocity of second glider = -2 m/s

= Final Velocity of first glider

= Final Velocity of second glider = 2 m/s

As the linear momentum of the system is conserved we have

The velocity of glider A is -0.4 m/s

= 0

= -5 m/s

= 0.92 m/s

The velocity of glider A is -3.552 m/s
