Answer:
The minimum time taken is 3.84 s.
Explanation:
The expression for the equation of motion is as follows;
v= u+at
Here, v is the final speed, u is the initial speed, a is the acceleration and t is the time.
Convert the initial speed from to .
Convert the final speed from to .
It is given in the problem that The brakes on your automobile are capable of creating a deceleration of . The sign of the acceleration is negative here as there is deceleration.
Calculate the minimum time by using equation of motion.
v= u+at
Put , and
21.11= 39.17+(-4.7)t
t= 3.84 s
Therefore, the minimum time taken is 3.84 s.
