At the instant shown, car A has a speed of 20km/h, which isbeing increased at a rate of 300km/h2 as the car entersan expressway. At the same instant, car B is decelerating at250 km/h2 while traveling forward at 100 km/h. Determine the velocity and acceleration of A with respect toB.
The diagram is a circle, with car A on the right side, headingclockwise. The radius is 100 m; no angle is given. Attached to the circle, on the left side, is a verticalexpressway. Car B is on this expressway, moving forward(up).
