Answer:
t = 6 [s]
Explanation:
In order to solve this problem we must first use this equation of kinematics.
where:
Vf = final velocity = 0 (the car comes to rest)
Vo = initial velocity = 72 [km/h]
a = acceleration [m/s²]
x = distance = 60 [m]
First we must convert the velocity from kilometers per hour to meters per second.
Now using this other equation of kinematics.
0 = 20-3.33*t
t = 6[s]

The speedometer on your vehicle indicates the c. instantaneous speed of your car. It shows “your speed at a particular instant in time.”
