Two carts A and B of equal mass mA = mB = 0.622 kg are on an air track. Cart A is moving with speed vi = 0.95 m/s towards cart B which is at rest. Cart A collides with cart B and the two stick together and move as one object after the collision. (Let the initial direct of cart A be positive.)
(a) What is the final speed of the two carts after the collision?
(b) What is the change in momentum of cart A?
(c) What is the change in momentum of cart B?
(d) What is the work done by non-conservative forces in this case?
(e) If you consider the two carts as the system, is the momentum of the two-cart system conserved?
(Yes, No, or cannot be determined)
(f) For the two-cart system, is the kinetic energy conserved?
(Yes, No, or cannot be determined)
