Question

Problem 9.13 A small, 300g cart is moving at 1.30m/s on an air track when it collides with a larger, 5.00kg cart at rest. After the collision, the small cart recoils at 0.820m/s .
What is the speed of the large cart after the collision? Problem 9.13 A small, 300g cart is moving at 1.30m/s on an air track when it collides with a larger, 5.00kg cart at rest. After the collision, the small cart recoils at 0.820m/s .

Explanation / Answer

Applying conservation of momentum equation we ve

(M1V1 + M2V2)initial = (M1V1 + M2V2)final

0.3*1.3 + 0 = 0.3*- 0.82 + 5*V2

V2 = (0.39+0.246)/5

= 0.1272 m/sec
