1. The problem statement, all variables and given/known data An Escort and a Camaro traveling at right angles collide and stick together. The Escort has a mass of 1100 kg and a speed of 25 km/h in the positive x direction before the collision. The Camaro has a mass of 1500 kg and was traveling in the positive y direction. After the collision, the two move off at an angle of 53 degrees to the x axis. What was the speed of the Camaro?(in km/h) 2. Relevant equations m1v1 + m2v2cos[tex]\theta[/tex] = (m1+m2)vfcos53 (??) 3. The attempt at a solution I have tried using the unknown theta as 90 degrees because they are traveling at a right angle to eachother, but that does not seem to work. I know that in an inelastic collision, kinetic energy is not conserved, but momentum is conserved. I know that the total momentum before the collision is the individual momentum of the two cars added together. I feel like I know little bits and pieces of information about this problem, but am unsure of how it relates to the problem. I had a very similar problem to this one where the second car was at rest and we used an equation similar to the one above. I am not sure what to do when the second car is actually moving! Thanks for any help!
