Question

A race car moves along a circular track at a speed of 0.512 m/s. If the car's centripetal acceleration is 15.4 m/s2, what is the distance between the car and the center of the track?

Answer 1

The radius is
`r = 0.0170 \ m`

Step-by-step explanation:

From the question we are told that

The speed at which the race car moves is
`v = 0.512 \ m/s`

The centripetal acceleration is
`a _r = 15.4 \ m/s`

Generally the centripetal acceleration is mathematically represented as

`a_r = (v^2 )/(r)`

=>
`15.4 = (0.512^2 )/( r)`

=>
`r = 0.0170 \ m`
