At the intersection of texas avenue and university drive, a yellow subcompact car with mass 950 kg traveling east on university collides with a red pickup truck with mass 1900 kg that is traveling north on texas and has run a red light (fig. e8.41). the two vehicles stick together as a result of the collision, and the wreckage slides at 16.0 m/s in the direction 24.0° east of north. calculate the speed of each vehicle before the collision. the collision occurs during a heavy rainstorm; ignore friction forces between the vehicles and the wet road.

Describe different biomes. what are some adaptations that organisms (plants or animals) must have to live in each biome?
