Answer:
The stopping distance is 36.15m
Explanation:
In this exercise we are going to apply the second equation of motion to model the situation
Given data
time in seconds= 4.6 seconds
speed v= 11 m/s
deacceleration a= 8.2m/s
Substituting this values into the expression for distance we have
The stopping distance is 36.15m
