1. The problem statement, all variables and given/known data
Two identical cars (m = 1350 kg) are traveling at the same speed of 25.0 m/s. They are moving in the directions shown in the drawing. What is the magnitude of the total momentum of the two cars? img:http://higheredbcs.wiley.com/legacy/...07_q1_03_1.gif A particle is moving along the +x axis, and the graph shows its momentum p as a function of time t. What is the magnitude of the net average force in regions A . Give your answer to two significant figures, e.g., 6.3 or 0.72. img: http://higheredbcs.wiley.com/legacy/...07_q1_08_1.gif 2. Relevant equations i don't know i'm confused. 3. The attempt at a solution please help me.thank you very much!!

For the first one, try splitting the momenta into x and y components and then finding the resultant x and y momenta
