A0.300kg glider is moving to the right on a frictionless, ­horizontal air track with a speed of 0.800m/s when it makes a head-on collision with a stationary 0.150kg glider. a) find the magnitude of the final velocity of first glider if the collision is elastic. b) find the direction of the final velocity of first glider if the collision is elastic. c) find the magnitude of the final velocity of second glider if the collision is elastic. d) find the direction of the final velocity of second glider if the collision is elastic. e) find the final kinetic energy of first glider. f) find the final kinetic energy of second glider.

The final velocity of the first glider is 0.27 m/s in the same direction as the first glider

The final velocity of the second glider is 1.07 m/s in the same direction as the first glider.

0.010935 J

0.0858675 J

Explanation:

= Mass of first glider = 0.3 kg

= Mass of second glider = 0.15 kg

= Initial Velocity of first glider = 0.8 m/s

= Initial Velocity of second glider = 0 m/s

= Final Velocity of first glider

= Final Velocity of second glider

As momentum and Energy is conserved

From the two equations we get

The final velocity of the first glider is 0.27 m/s in the same direction as the first glider

The final velocity of the second glider is 1.07 m/s in the same direction as the first glider.

Kinetic energy is given by

Final kinetic energy of first glider is 0.010935 J

Final kinetic energy of second glider is 0.0858675 J

i believe the answer is a

i think they are all correct

explanation:

they seem good
