On an air track, a 403.0 glider moving to the right at 2.30 collides elastically with a 501.0 glider moving in the opposite direction at 3.00 .Find the velocity of first glider after the collision

1 answer

Given:
M1 = 0.403kg, V1 = 2.30 m/s.
M2 = 0.501kg, V2 = -3.00 m/s.

V3 = (V1(M1-M2) + 2M2*V2)/(M1+M2).
V3 = (2.3(0.403-0.501)+1.002*(-3.0))/0.904 = -3.57 m/s = Velocity of M1 after collision.

V3 is moving to the left.
