A 1250 kg car is moving down the highway with a velocity of 32. 0 m/s when it bumps into the car ahead of it which has a mass of 875 kg and a velocity of 25. 0 m/s. After the collision, the two cars stick together. What will be the resulting velocity of the two cars together? how much energy will be lost in this collision?.

Layer r contains a well-known index fossil that is 100 million years old. based on this information and the principle of superposition, a. layers t and m are older than 100 million years, and layers x and g are younger than 100 million years. b. layers t, m, x, and g are all older than 100 million years. c. layers t and m are younger than 100 million years, and layers x and g are older than 100 million years.
