A car is traveling with a velocity of 17 m/s on a straight horizontal highway. The wheels of the car have a radius of 48 cm. If the car then speeds up with an acceleration of 2 m/s≤ for 5 s, determine the number of revolutions of the wheels during this period.

calculus
A car is travelling at 90mph when its brakes are fully applied, producing a constant deceleration of 22 ft/sec2. Find the distance covered by the car before it comes to a stop. (Remember: 60 mph equals 88 ft/sec.)
