At the intersection of Texas Avenue and University Drive, a yellow, subcompact car with mass 950 kg traveling east on University collides with a maroon pickup truck with mass 1900 kg that is traveling north on Texas and ran a red light . The two vehicles stick together as a result of the collision and, after the collision, the wreckage is sliding at 16.0 m/s in the direction 24 degrees east of north. The collision occurs during a heavy rainstorm; you can ignore friction forces between the vehicles and the wet road.
A) Calculate the speed of the car before the collision.
B) Calculate the speed of the truck before the collision.
