PLEASE HELP!!! Part 1) Items "a" through "i" below describe 9 graphs. If all of the speeds are positive, what would each graph look like? Write the words flat line, sloping up, curving up, or curving down.

Part 2) Assume all the speeds are negative.

A2 kg ball travellng to the right with a speed of 4 m/s collidees with a 5 kg ball traveling to the left with a speed of 3 m/s. take right to be the positive direction. what is the total momentum of the two balls before they collide? what is the total momentum of the two balls after they collide?
