A 3.00 kg cart moving with a velocity of 20.0 m/s collides with a stationary 5.00 kg cart. After the collision, the second cart has a velocity of 14.0 m/s.

a) List the givens.

b) What is the momentum of each cart before the collision?

c) What is the total momentum before the collisions?

d) What is the momentum of each cart after the collision?

e) What is the magnitude and direction of the velocity of the first cart now?

i need with 1.3.2 investigate cycling o2 and co2 apex

we need to see it
