Arace car traveling at a consistent speed of 50 m s drives around a circular track that is 500 m in diameter what is the magnitude of the radial acceleration of the car

Explanation:

The radial acceleration (also  called centripetal acceleration) of an object in circular motion is given by

where

v is the speed of the object

r is the radius of the circular path

For the car in this problem,

v = 50 m/s

we know that the diameter of the track is d = 500 m, so the radius is

And so, the radial acceleration is

this allows people to make the best decision or pursue the best option. when alternatives are weighed using their advantages and disadvantages, the option whose disadvantages outweigh the advantages (based on a qualitative or quantitative analysis) are shunned while those whose advantages outweigh their disadvantages are pursued.
