Given the angular acceleration in the previous problem, how many revolutions does one of the car’s wheels complete in 10.0 s? Assume the car is initially at rest.

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h
