Two ice skaters stand together as illustrated in Figure (a) below. They "push off" and travel directly away from each other, the boy with a velocity of v = 0.760 m/s to the left. If the boy weighs 715 N and the girl weighs 480 N, what is the girl's velocity (in m/s) after they push off? (Consider the ice to be frictionless.)
Train cars are coupled together by being bumped into one another. Suppose two loaded train cars are moving toward one another, the first having a mass of 130,000 kg and a velocity of 0.300 m/s, and the second having a mass of 105,000 kg and a velocity of -0.120 m/s. (The minus indicates direction of motion.) What is their final velocity?

You have been hired as an expert witness in a court caseinvolving an automobile accident. The accident involvedcar A of mass 1500 kg which crashed into stationary car Bof mass 1100 kg. The driver of car A applied his brakes15 m before he skidded and crashed into car B. After thecollision, car A slid 18 m while car B slid 30 m. The coefficient of kinetic friction between the locked wheels and the road was measured to be 0.60. Show that the driver of car A was exceeding the 55 mi/h (90km/h) speed limit before applying the brakes.
