A car started at point A and traveled around the track in a clockwise direction. Point B is halfway around the track. The car reached point B 30.0 seconds after it left point A. The car's speedometer indicated a speed of 35.0 m/s when the car reached point B. The car reached point A 20.0 seconds after passing point B. The car's speedometer indicated a speed of 40.0 m/s when it reached point A

a) What was the car's instantaneous speed at point B?

b) What distance did the car travel when it went from point A to point B?

c) Calculate the car's average speed as it moved from point A to point B.

d) Determine the car's displacement 30.0 seconds after it left point A.

e) Calculate the car's average velocity as it moved from point A to point B.

f) What distance did the car travel when it went from point A back to point A?

g) Calculate the car's average speed as it moved from point A back to point A.

h) Determine the car's displacement 50.0 seconds after it left point A.

i) Calculate the car's average velocity as it moved from point A back to point A.
