  1. An automobile is traveling at v0 = 30 meters per second, when the driver applies the brakes, bringing it to rest in T = 8 seconds. The radius of its wheels is r = 40 cm. Assume that the deceleration is constant, and that the wheels do not slip on the road.

    • Determine the deceleration −a of the automobile.

    • Determine the distance D traveled by the auto during deceleration.

    • Determine the number of revolutions N made by the wheel during the deceleration.

Help with detailed explanation of solutions pls and thank you!

An automobile is traveling on a long, straight highway at a steady 77.0 mi/h when the driver sees a wreck 200 m ahead. At that instant, she applies the brakes (ignore reaction time). Between her and the wreck are two different surfaces. First there is 100 m of ice, where the deceleration is only 1.30 m/s2 . From then on, it is dry concrete, where the deceleration is a more normal 7.60 m/s2 Part A. What was the car’s speed...
