Question

A car is traveling around a circular track. If the car traveling at a velocity of 15 m/s, what is the centripetal acceleration
of the car?
TE 10m

Answer 1

The centripetal acceleration  of the car is equal to $22.5 \;m/s^2$.

Given the following data:

• Radius, r = 10 meter

• Speed, V = 15 m/s.

To determine the centripetal acceleration  of the car:

Mathematically, the centripetal acceleration of an object is given by the formula:

$A_c = \frac{V^2}{r}$

Where:

• $A_c$ is the centripetal acceleration.

• r is the radius of the circular track.

• V is the velocity of an object.

Substituting the given parameters into the formula, we have;

$A_c = \frac{15^2}{10}\\\\A_c = \frac{225}{10}\\\\A_c = 22.5 \;m/s^2$
