A 950-kg red car (Figure 1) with a speed of v1 = 20.0 m/s approaches an intersection, traveling in the positive x direction. A 1300-kg blue minivan is heading for the same intersection in the positive y direction. The car and minivan collide and stick together, producing wreckage that moves at an angle of θ = 40.0∘ relative to the positive x axis.
