Question

The tires of a car make 75 revolutions as the car reduces its speed uniformly from 90.0 km/h to 59.0 km/h . the tires have a diameter of 0.90 m how far does the car go

Answer 1

To determine how far the car goes, we have to know the distance covered by the 75 revolutions of the tires of the car. To do this, we have to calculate for the perimeter of the tire, then multiply it to the number of revolutions.

Distance =
`75 \pi d`

where pi*d is the circumference of the tire

Distance = 75 * pi * 0.90 m
Distance = 212.06 m

The car covers a distance of 212.06 m as it slows down.
