How will you investigate a change in velocity affects the velocity of the two carts after the collision if the objects do not stick together?

P = mv

This is a momentum question:

Momentum is always conserved so the momentum before and after a collision must be equal so:

The velocity of the two objects after they collide and dont stick together if no KE is lost is dependent on the mass of each of the objects by:

Where i is initial and f is final meaning before and after the collision

significant amounts of nitrogen oxides, carbon monoxide, and other pollution

explanation:

passenger vehicles are a major pollution contributor, producing significant amounts of nitrogen oxides, carbon monoxide, and other pollution. in 2013, transportation contributed more than half of the carbon monoxide and nitrogen oxides, and almost a quarter of the hydrocarbons emitted into our air.

your answer should be c) enjoy!
