System Open or Closed
System Open or Closed#
Two trucks collide on a track. Truck A comes up behind truck B and runs into it. Truck A has mass of 50 kg, truck B has mass of 346 kg. The following graph shows the velocity of each truck as a function of time.
Is the system isolated? Why or why not?
Yes, because the two carts are on a track with no friction.
Yes, because their change in velocities are the same.
No, because the total momentum is nonzero.
No, because the momentum is not conserved
