Alright let's start this off with our basic equation!
Accerlation (a) = ?
Initial velocity (V1)= 60 mph = 88 ft/s (because we HAVE to convert mph to ft/s to match time)
Final velocity (V2) = 0 ft/s because the car stops
Time (t) = 4 seconds
a = [tex] \frac{Final velocity - Initial Velocity}{time} [/tex]
a = [tex] \frac{0 - 88}{4} [/tex]
a = [tex] \frac{-88}{4} [/tex]
a = -22
Therefore, your acceleration is -22 ft/s² !! Hope this helped and was one of the branliest answers :')
