racing on a flat track, a car going 32 m/s rounds a curve 56m in radius. what is the car's centripetal acceleration?

still helping people 10 years later :)

Ac = v^2/R = [ 32*32/56] m^2/s

I don't know

To calculate the car's centripetal acceleration, we can use the formula:

Centripetal acceleration (a) = (velocity (v))^2 / radius (r)

Given:
Velocity (v) = 32 m/s
Radius (r) = 56 m

First, square the velocity:
v^2 = (32 m/s)^2 = 1024 m^2/s^2

Next, substitute the values into the centripetal acceleration formula:
a = (1024 m^2/s^2) / 56 m

Now, divide to get the result:
a ≈ 18.286 m/s^2

Therefore, the car's centripetal acceleration is approximately 18.286 m/s^2.
