Physics

You push a 2 kg cart giving it a speed of 2 m/s moving in the negative direction and at the same time your lab partner pushes on a 3 kg cart giving it a speed of 2 m/s moving in the positive direction. The two carts collide but do not stick together. A sensor on the 3 kg cart states that it experienced an impulse of -6 kg*m/s.


(a)Draw a side view diagram of the two carts just before the collision. Draw in velocity arrows on each cart before the collision. Also write in the speed of each cart next to its velocity arrow


(b)What is the impulse that acted on the 2 kg cart?
Impulse on 2 kg = _______________ 


(c) What is the velocity of each cart after the collision? ????2???????? ′ = _______________ ????3???????? ′ = ________________ 


(d)Assuming that the collision lasted for exactly 0.25 s, what was the average force vector acting on the 2 kg cart during the collision? FAvg = _______________
