Two trains depart at the same time, heading toward each other on parallel tracks. The stations are 5 miles apart. One train accelerates at a rate of 8 mi/hr/s while the other train accelerates at a rate of 9 mi/hr/s. How long does it take the trains to pass each other?

How fast is each train moving as they pass each other?

Two trains are approaching each other on adjacent tracks each running with a constant velocity of 10 m/s. When they are at a distance of 90 m, a bird flying right with one of the train engines decides to go ahead towards the other train with double the speed of the train. As soon as it reaches the other train, it turns around without landing and flies back to the train it started from. How many times can the bird...

A person is standing at a train station, and two identical trains are passing each other 100 m down the tracks. Train A is moving away from him at 20 m/s, and train B is moving toward him at 20 m/s. As the trains pass each other, they emit identical pulses of sound from their horns. At the instant that the pulses are sounded, the trains' horns are both precisely 100 m away from him. What will the person hear?...

Two buses are driving along parallel freeways that are 20 mi apart, one heading east and the other heading west. Assuming that each bus drives a constant 50 mph, find the rate (in mph) at which the distance between the buses is changing when they are 29 mi apart, heading toward each other.

Two wires are parallel, and one is directly above the other. Each has a length of 38.6 m and a mass per unit length of 0.0267 kg/m. However, the tension in wire A is 47.3 × 102 N, while the tension in wire B is 1.50 × 102 N. Transverse wave pulses are generated simultaneously, one at the left end of wire A and one at the right end of wire B. The pulses travel toward each other. How much...

Two boys are sliding toward each other on a frictionless, ice-covered parking lot. Jacob, mass 45 kg, is gliding to the right at 8.19 m/s, and Ethan, mass 31.0 kg, is gliding to the left at 10.7 m/s along the same line. When they meet, they grab each other and hang on. (a) What is their velocity immediately thereafter? (b) What fraction of their original kinetic energy is still mechanical energy after their collision? (c) That was so much fun...
