A car goes around a curve at 20. m/s. If the radius of the curve is 40 m, what is the centripetal acceleration of the car?

The centripetal acceleration of car is 8 m/s².

Explanation:

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

answer: (431,2)
