Awheel has a radius of .30m. it rotates 185 times before it stops.
how far did the vehicle travel?

Here is the sollution:

During one rotation the wheel covers the distance of its circumference that can be counted with formula:

in which r is radius, then:


We know that it rotates 185 times so you need to multiply the wheel's circumference by 185 to get total distance (D):

The answer is that the vehicle traveled 348,54 m far.

The circumference of any circle is  (2 pi) x (radius) .

185 times the circumference of a circle is  (185) x (2 pi) x (radius) .

If the wheel doesn't slip, then it rolls (185) x (2 pi) x (0.3 m) = 348.72 m (rounded)

Newton's first law describes something special that results from the sum of all the external forces (including gravity) on an object.
