Two cars are travelling east along a straight highway at the same speed. At an intersection, the highway branches and splits into two straight roads, one heading approximately north-east and one heading approximately south-east. The angle betwen the two roads is 60 degrees. The two cars leave the intersection at the same time, one travelling north-east at 100 km/h and the other travelling south-east at 80 km/h. How fast is the distance between the two cars changing 30 minutes after they leave the intersection.

A Ford passes a Toyota on the road (both vehicles are traveling in the same direction). The Ford moves at a constant speed of 35.9 m/s. Just as the Ford passes it, the Toyota is traveling at 16.8 m/s. As soon as the Ford passes the Toyota, the Toyota begins to accelerate forward at a constant rate. Meanwhile the Ford just keeps going at a steady 35.9 m/s to the east. The Toyota catches up to the Ford a distance of 101.4 m ahead of where the Ford first passed it. What was the magnitude of the Toyota s acceleration? 6.8 m/s^2 2.5 m/s^2 13.5 m/s^2 5.0 m/s^2

A treasure hunter follows a map moving 25 km [N], 37 km [W 37 degrees S], 63 km [E 65 degrees S] and finally 15 km [N 17 degrees E]. If his average for the entire trip was 45 km/hr, calculate: a. The total time for the trip; and b. The average velocity of the trip
A speeder travelling at a constant velocity of 40 m/s passes by a police car that is initially at rest. Soon afterwards, the police officer starts moving towards the speeder with an uniform acceleration of 5.33 m/s2. What is the position of both cars, in meters, when the police officer catches the speeder? Take the initial position of the officer as the origin of the x-axis.
A Boeing 747 "Jumbo Jet" has a length of 64.5 m. The runway on which the plane lands intersects another runway. The width of the intersection is 24.8 m. The plane decelerates through the intersection at a rate of 5.56 m/s2 and clears it with a final speed of 43.1 m/s. How much time is needed for the plane to clear the intersection?

George, the absent-minded professor, drives his car 5.0 miles due east alonga straight road to the grocery store. Upon arriving there 15 minutes (0.25 h) after he left home, he suddenly realizes he forgot his grocery list. He immediately turns around and heads back towards home. After travelling 6.8 miles due west in 12 minutes (0.20 h), the car runs out of gas. What is his average speed during the not-quite-completed trip?
