    Calculating Speed of Cars Prior to Collision: Mass, Velocity After Impact

    Yeah, what I am missing is what it's asking me to find.

    Calculating Speed of Cars Prior to Collision: Mass, Velocity After Impact

    Well, that's not good news. Are there any formulae I can use?

    Calculating Speed of Cars Prior to Collision: Mass, Velocity After Impact

    So, after I break up the V1' and V2' velocities into horizontal and vertical vectors, can I solve for all four using those formulas? Aslo, what do I do about the velocities being negative since M_{1}-M_{2} is negative?

    Calculating Speed of Cars Prior to Collision: Mass, Velocity After Impact

    What about getting the right directions? When I use those equations the velocity comes out to be negative. Do I just switch the direction?

    Calculating Speed of Cars Prior to Collision: Mass, Velocity After Impact

    I think these are the formulas, but I'm not sure. V_{1}=\left(\begin{array}(\underline{(M_{1}+M_{2})}\\(M_{1}-M_{2})\end{array}\right)V_{1}' V_{2}=\left(\begin{array}({(2M_{1})}\\\overline{(M_{1}-M_{2})}\end{array}\right)V_{2}' Can anyone help?

    Calculating Speed of Cars Prior to Collision: Mass, Velocity After Impact

    Two cars collide at an intersection. The first car has a mass of 925kg and was traveling north. The second car has a mass of 1075kg and was traveling west. Immediatly after impact, the first car had a velocity of 52km/hr, 310deg, and the second car had a velocity of 40km/hr, 320deg. What was the...
