A car with a mass of 1040 kg and a speed of v1 = 15.0 m/s
approaches an intersection, as shown in the figure. A 1270 kg
minivan traveling at v2 is heading for the same intersection. The
car and minivan collide and stick together. The direction of the
wreckage after the collision is theta=40.0 degrees above the x
axis.
Part A) Find the initial speed of the minivan, assuming external
forces can be ignored (in m/s).
Part B) Find...
