A car is traveling with a speed of 25 m/s along a straight, horizontal road. Each wheel has a radius of .25 m. If the car speeds up with a linear acceleration of 2.0 m/s^2 for 6.0 s. Find the angular displacement of each wheel during this time in revolutions.

Car's displacement= S = ut + at^2/2

= 25*6 + 2*6^2/2

= 150 + 36 = 186m

One rev. of wheel covers = 2*pi*r

No. of revolutions = 186/(2*pi*0.25)

= 118.4 rev.
