A 1000 kg car goes around a turn in the road that has a radius of curvature of 50 m. The car is traveling at a constant speed of 12 m/s. Is the car accelerating? Why or why not? What is the direction of the acceleration?

A body accelerates only when there is change in its magnitude or direction . and here

even if the magnitude is not changing ( remains constant ) the direction changes , hence the car is accelerating.

and since the car turns it's direction keep changing.

a and c

c is 100% but i am confused in a

amplitude

hope this
