Train A is traveling at a constant speed VA = 40 mi/hr while car B travels in a straight line along the road as shown at a constant speed VB. A conductor C in the train begins to walk to the rear of the train car at a constant speed of 6 ft/sec relative to the train. If the conductor perceives car B to move directly westward at 20 ft/sec, how fast is the car traveling? B UB AE Answer: Vg= i L-- e-N -C mi/hr

Question 8 A car is traveling around a circular track of 680-ft radius. If the magnitude of its total acceleration is 9.5 ft/sec2 at the instant when its speed is 40 mi/hr, determine the rate at at which the car is changing its speed.

Car A is traveling at a location where the speed limit is 100 km/h. The police officer in car Pobserves this speed via radar. The driver of car A is traveling at VA = 138 km/h as it passes P, but over the next 4.3 seconds, the car uniformly decelerates to the speed limit of 100 km/h, and after that the speed limit is maintained. At the moment when A passes P, the police car begins to accelerate at the constant rate of 5.0 m/s² until a speed of 167 km/h is achieved, and that speed is then maintained. Determine the distances required for the police officer to overtake car A. Answer: s= i m

Train A is traveling at a constant speed VA = 35 mi/hr while car B travels in a straight line along the road as shown at a constant speed VB. A conductor C in the train begins to walk to the rear of the train car at a constant speed of VC/A = 4 ft/sec relative to the train. If the conductor perceives car B to move directly westward at VB/C = 15 ft/sec, how fast is the car traveling? B UB | N x C
