Question 494223: A train is traveling with an initial velocity of 20.1 m/sec. If the brakes can apply a maximum acceleration of -.0500 m/sec^2, how long will it take the train to stop? Answer by chessace(471) (Show Source):
You can put this solution on YOUR website! If "how long" means Time, just divide (-)V / A.
Keep units to make sure:
(-20.1 m/s) / (-0.0500 m/(s^2))
= (20.1/0.0500) sec
= 402 sec. = 6 Min 42 Sec.
