n lab you investigated collisions between carts on a low-friction track. Imagine initially one of he carts (m1 = 250g) moved with a speed of v1 vas initially at rest. Here, as always, please show your work and explain your answers using the laws of physics. In ther words, don't just rely on intuition and experience.) a) If this was a perfectly elastic collision, what would you expect the velocities of the carts to pe after the collision? b) What was the velocity of the center of mass before the collision? What is the velocity of the enter of mass after the collision? (Explain!) = 3m/s to the right and the other (m2 = 500g)

In lab you investigated collisions between carts on a low-friction track. Imagine initially one of the carts (m1 = 250g) moved with a speed of vi = 3m/s to the right and the other (m2 = 500g) was initially at rest. (Here, as always, please show your work and explain your answers using the laws of physics. In other words, don't just rely on intuition and experience.) (a) If this was a perfectly elastic collision, what would you expect the velocities of the carts to be after the collision? (b) What was the velocity of the center of mass before the collision? What is the velocity of the center of mass after the collision? (Explain!)
