The total stopping distance for a car traveling at a speed of 30 m/sec is 65 m, including a reaction time of 0.5 sec during which the car travels at constant speed before braking.
a) Draw a motion diagram for the problem.
b) What is the deceleration of the car while braking?
c) What is the total stopping distance for the car if the initial speed is 40 m/sec? Assume the same reaction time and deceleration.
