Arace car travels a circular track at an average rate of 135 mi/hr. the radius of the track is 0.450 miles. what is the centripetal acceleration of the car?

Answer : .

Explanation :

It is given that,

Velocity of a race car, v = 135 mi/hr

Radius of the track, r = 0.45 miles

We know that the centripetal acceleration is defined as :

r is the radius of the circle.

So, the centripetal acceleration of the car is .

Hence, this is the required solution.

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

hope that !                                         : )

this would be about 43%
