    1. The problem statement, all variables and given/known data
    On a supermarket parking lot, a car is pulling out and bumping into an oncoming car. The car pulls out with 0.8 m/s, while the oncoming car has a speed of 1.2 m/s. The angle between the velocities is 24 degrees, as indicated in the figure. What is the collision speed?

    2. Relevant equations

    3. The attempt at a solution

    Welcome to PF!

    Hi melmel7880! Welcome to PF! :wink:

    Relative velocities are vectors, so use a vector triangle …

    you are given the lengths of two sides, and the angle between, and you want the third length …

    what do you get? :smile:
