An airliner passes over an airport at noon traveling 510 mi divided by hr due west. At 1 : 00 p.m., another airliner passes over the same airport at the same elevation traveling due north at 570 mi divided by hr. Assuming both airliners maintain their (equal) elevations, how fast is the distance between them changing at 2 : 30 p.m.

A driver is traveling 70 mi/hr on a road with a -2% downgrade. The driver’s vehicle has a braking efficiency of 90% and has anti-lock brakes. There is a stalled car on the road 500 ft ahead of the driver. The road is in good condition and is initially dry, but is wet for a 200 ft stretch just before the stalled car. What is the maximum allowable perception-reaction time of the driver such that she can still stop before...

A car is traveling up a 1.5% grade at 65 mi/hr on good, wet pavement. The driver brakes to try to avoid hitting a cone on the road that is 300 ft ahead. The driver’s reaction time is 1.5 second. When the driver first applies the brakes, a software flaw causes the braking efficiency to lower to 0.8 for 100 ft. After the initial 100 ft, the braking efficiency returns to 1.0. How fast will the driver be going when...

An airplane pilot wishes to fly to his destination 500 mi due west, but the wind is blowing at 23.1 mi/hr toward 14.1° north of west. The speed of the plane relative to the air is 166.5 mi/hr. At what angle (south of west) must the pilot orient the plane in order to fly to his destination directly? If the pilot orients the plane at that angle, what will be the speed of the plane relative to the ground?

A road heading due east passes over a small hill. You drive a car of mass mat constant speed over the top of the hill, where the shape of the roadway is well approximated as an arc of a circle with radius R. Sensors have been placed on the road surface there to measure the downward force that cars exert on the surface at various speeds. The table gives values of this force versus speed for your car is shown...
