A car travels on a circular track of radius \( R=204 \mathrm{~m} \), with constant speed \( v 0=34.0 \mathrm{~m} / \mathrm{s} \). Calculate the radial component of acceleration, ar.

Step 1 ：The radial component of acceleration, ar, can be calculated using the following formula:

Step 2 ：ar = (v0)^2/R

Step 3 ：Substitute the given values into the formula:

Step 4 ：ar = (34.0 m/s)^2/(204 m)

Step 5 ：ar = 577.6/204 m/s^2

Step 6 ：ar = -2.83 m/s^2

Step 7 ：The negative sign indicates that the acceleration is directed towards the center of the circular track.

Step 8 ：Convert the magnitude of ar to two decimal places:

Step 9 ：ar = -5.92 m/s^2.
