Starting from rest at point A, you ride your motorcycle north to point B 75.0 m away, increasing speed at a steady rate of 2.00m/s^2. You then gradually turn toward the east along a circular path of radius 50.0 m at constant speed from B to point C, until your direction of motion is due east at C. you then continue eastward, slowing at a steady rate of 1.00 m/s^2 until you come to rest at point D.

2. What distance did you travel for the entire trip from A to D?
3. What is your average velocity and acceleration for the trip from A to D?
