Problem
A 2.0kg cart slides at 1.8m/s toward an identical cart at rest on a horizontal track. During the 0.030s that the carts remain in contact, a constant 0.12N breeze acts opposite to the motion. Calculate the percentage change in the two-cart system’s momentum that this external force could cause during the collision.
