A car with a mass of 980 kg and a speed of v1 = 17.0 m/s approaches an intersection, as shown in the figure(Figure 1) . A 1300 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 θ = 41.5 ∘ above the x axis.

Question

A car with a mass of 980 kg and a speed of v1 = 17.0 m/s approaches an intersection, as shown in the figure(Figure 1) . A 1300 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 θ = 41.5 ∘ above the x axis.
Find the initial speed of the minivan, assuming external forces can be ignored.
Part B
Find the final speed of the wreckage.
