Question

A 1,500-kg car traveling east with a speed of 25.0 m/s collides at an intersection with a 2,500-kg van traveling north at a speed of 20.0 m/s. Find the direction and magnitude of the velocity of the wreckage after the collision, assuming that the vehicles undergo a perfectly inelastic collision (that is, they stick together). and assuming that friction between the vehicles and the road can be neglected. (v=15.6 m/s, = θ=53.1°)
