Three carts of masses *m*_{1} = 4.50 kg, *m*_{2} = 9.50 kg, and *m*_{3} = 3.00 kg move on a frictionless, horizontal track with speeds of *v*_{1} = 7.00 m/s to the right, *v*_{2} = 3.00 m/s to the right, and *v*_{3} = 5.50 m/s to the left, as shown below. Velcro couplers make the carts stick together after colliding.

(a) Find the final velocity of the train of three carts.

(b) Does your answer require that all the carts collide and stick together at the same moment?

What if they collide in a different order?

Step 1

a)

According to law of conservation of linear momentum,

Step 2

Substitute the values in (I) and rearrange in terms of v

Step 3

The final velocity is 4.5...
