What is the work done by non-conservative forces

Reference no: EM13510403

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?

(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)
