Answer: the car's acceleration is 5.476 m/s^2

Step-by-step explanation:

We want to calculate the centripetal acceleration of the car. The formula for calculating centripetal acceleration is expressed as

A = V^2/R

where

A = centripetal acceleration

V is the velocity of the car

R is the radius of the car

From the information given,

V = 37 m/s

R = 250m

By substituting these values into the formula,

A = (37 m/s)^2/250m

A = 1369m^2/s^2/250m

A = 1369/250 * m^2/ms^2

the m would cancel out. One m remains in the numerator. Thus,

A = 5.476 m/s^2

the car's acceleration is 5.476 m/s^2
