A) Determine the car's speed.

--Found this answer to be 5.35 m/s which is correct

B) What is the magnitude and direction of the acceleration when the car is at point B?

magnitude:____m/s

Direction:___*counterclockwise for the x+ axis

Part B is where I am completely lost.

**drwls**, Tuesday, March 6, 2012 at 11:59pmThe acceleration is V^2/R.

R is the radius of the arc. V is the speed you already computed.

The direction of acceleration is towards the center of the circular arc. At B, that would appear to be 145 degrees counterclockwise from the +x axis.
