How long does it take the car to come to rest? Solution Solution v i = 60 mph x - axis a = -10 mph/s v a t = 60 10 / mph mph s t-- = 10 / 60 mph s t mph- = - 60 10 / mph t mph s- =- 6 t s = v f = 0 mph v = v f v i = 0 60 = -60 mph Example Example A car is traveling at a speed of 60 mph when the driver applies the brakes and decelerates at a rate of 10 mph/s. How far does the car travel before it comes to rest? Example Example x - axis Speed Time Distance Traveled = Speed Time Taken = Area under Graph Example Example Speed Time Distance Traveled = Area under Graph = Height Base = 60 mph 6 s 1 60 miles = 6 s 2 hour 1 60 1609 m = 6 s 2 3600 s =80.45 m =80.45 3.281f t =264 f t 1 mile = 1609 m 1 m = 3.281 ft 1 hour = 60 min. = 3600 s The Equations of Motion The Equations of Motion What do we care about knowing?
