A car with a mass of 950 kg and an initial speed of v1 = 21.5 m/s approaches an intersection, as shown in the figure. A 1300 kg minivan traveling northward is heading for the same intersection. The car and minivan collide and stick together. If the direction of the wreckage after the collision is 43.0° above the x axis.
Find the initial speed of the minivan and the final speed of the wreckage, m/s.

(950kg)(21.5)=(1300)(Vi van)
Vi van = (950*21.5)/1300
Vi Van = 15.71 m/s

I don't know how to find the second part.
Can someone answer this ? I was here looking for that answer myself.

Nevermind above that's a wrong approach
