The driver of a car traveling at 17.7 m/s ap-
plies the brakes and undergoes a constant
deceleration of 1.38 m/s.
how many revolutions does each tire make
before the car comes to a stop, assuming that
the car does not skid and that the tires have
radii of 0.42 m?
answer in units of rev.

43 revolutions.

Explanation:

The time it takes for the car to stop is

The distance it travels in that time is

The number of revolutions that the tires make is then

The last calculation just asks the question "how many tire circumferences fit into d=113 meters?"

i don’t know what the answer is i wish i

the closer the planet is to the sun, the larger the gravity
