The brakes of a car

  1. Jan 3, 2010 #1
    the brakes of a car can slow it down from 60 mi/hr to 40mi/hr in 2 s. how long will it take to bring the car to a stop from an initial velocity of 25 mi/hr at the same acceleration?

    You have 60 peanuts and you can eat them so fast, that in 2 seconds you have 40.

    Hint: That's means you can eat 20 peanuts in 2 seconds!!

    At that speed, how long will it take you to eat 25 peanuts?

    Assuming a constant rate of peanut consumption.
