Car A is traveling at the constant speed of 45 km/h as it rounds the circular curve of radius r = 380 m and at the instant represented is at the position 0 = 40°. Car B is traveling at the constant speed of 54 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 with the pole moving with B. For this instant determine VA/B and the values of r and as measured by an observer in car B. Answers: VA/B = r = 0 = i i 8 m/s m/s rad/s B
Under the action of force P, the constant acceleration of block B is 6.2 ft/sec² up the incline. For the instant when the velocity of B is 3.1 ft/sec up the incline, determine the velocity of B relative to A (positive if up the slope, negative if down), the acceleration of B relative to A (positive if up the slope, negative if down), and the absolute velocity of point C (positive if up the slope, negative if down) of the cable.

2. A car is initially traveling along a horizontal circular path with radius of 400 ft as shown at a velocity of 30 miles/hour (mph). When the driver hits the pedal, the car accelerates at a constant rate. It is observed that when the car has traveled a total distance of 300 ft, its speed increases to 40 mph. Determine the total acceleration of the car when it reached this speed of 40 mph. -400 ft
