Question

On a frictionless air track, a 0.155 kg glider moving at 1.30 m/s to the right collides with and sticks to a stationary 0.250 kg glider.

Part A

What is the net momentum of this two-glider system before the collision?

Part B

What must be the net momentum of this system after the collision?

Part C

Why?

Essay answers are limited to about 500 words (3800 characters maximum, including spaces).

Part D

Use your answers in Parts A and B to find the speed of the gliders after the collision.

Part E

Is kinetic energy conserved during the collision?

Pi = mvi = .155 * .1.3 = .2015 Ns

b) As per the law of conserevation of linear mometum Pi = Pf

Hence the final mometum should be = .2015 Ns

c) Find velocity will be

.2015 = v (M1+M2)

v = .2015 /.405 = 0.497 m/s

d) KE is not conserved.
