Question 1163573: A car is driving at an initial velocity of +24m/s. If its brakes can supply an acceleration of -5.0m/s^2, how much time will be required to bring the car to a stop? Answer by ikleyn(52803) (Show Source):
It is well known from Physics (and from common sense, too, if you know definitions) that the time to stop
t = ,
where t is the time to stop, v is initial speed and "a" is deceleration value (taken by modulus).
So, t = = 4.8 seconds. ANSWER
