The Giant Ferris Wheel has a radius of 30meters. Assuming that a time t= t_0 , the wheel rotates counterclockwise with a speed of 40m/min, and is slowing at a rate of 15m/min^2 . Find acceleration vector for a person seated in a car at the lowest point of the wheel.

How to find acceleration vector?

And i don't get what does it meant by acceleration vector is.

"confuse"

Please give a hand. Thank You.
