Two trains travel on parallel tracks in the same direction. The first train has a length of 100m and velocity of 200kph. The second train has a length of 120m and velocity of 250kph. Their clear distance is initially 800 meters. (Hint: Solve for the relative velocity of two bodies) How long will it take for the second train to reach the rear of the firstHow long will it take for their front to be abreast.How long will it take for the second train to fully overtake the first.
A swimmer travels at 0.8 m/s heading south across a small lake. At the same time, a second swimmer heads north from the opposite shore at a speed of 0.4 m/s. How wide is the lake if the two swimmers meet 12 min later?
A red train traveling at 72 miles/hour (mph) and a green train traveling at 100 mph are headed toward one another along a straight, level track. When they are 2500 feet apart, each engineer sees the other's train and applies the brakes. The brakes decelerates each train at the rate of 2.0 meters per second squared. Is their a collision? If so, what is the speed of each train at impact? If not, what is the separation between the trains when they stop? Give the given and solution:
