Car A is traveling at the constant speed of 58 km/h as it rounds the circular curve of 350-m radius and at the instant represented is at the position θ = 42°. Car B is traveling at the constant speed of 69 km/h and passes the center of the circle at this same instant. Car A is located with respect to car B by polar coordinates r and θ with the pole moving with B. For this instant determine vA/B and the values of r˙ and θ˙ as measured by an observer in car B. Write vA/B in terms of the polar coordinates. Answer: vA/B = ( ___ er +____ eθ) m/s
A car and a truck are both traveling at the constant speed of 35 mi/h; the car is 40 ft behind the truck. The driver of the car wants to pass the truck, i.e., he wishes to place his car at B , 40 ft in front of the truck, and then resume the speed of 35 mi/h. The maximum acceleration of the car is 5 ft/s2 and the maximum deceleration obtained by applying the brakes is 20 ft/s2. What is the shortest time in which the driver of the car can complete the passing operation if he does not at any time exceed a speed of 50 mi/h? Draw the v-t curve.

-Car A moving at a constant velocity of 25 m/sec passes a gasoline station. At the same instant, car B leaves the same gasoline station and travels the same direction as that of car A. Determine the required acceleration of car B in order to overtake car A after 35 seconds. -Two cars A and B are travelling in the same direction with a velocity of 30 m/sec. Car A is 250 meters behind car B. After 17 seconds, car B decelerates at a constant rate. Determine the deceleration of car B so that car A can overtake after 17 seconds.
For a production shoot, camera A travels next to car B at the same velocity v=30 mph on a straight road. Car B then enters a curve without change in speed while camera A continues along a staight path and stays due west of car B so that car B always appears to be traveling due east from camera A. (The value between r and -x is theta=50 degrees) -What is the difference in speed between camera A and car B? -What is the speed of car B relative to camera A?
