I Review Car B is traveling a distance d ahead of car A. Both cars are traveling at 60 ft/s when the driver of B suddenly applies the brakes, causing his car to decelerate at 12 ft/s², It takes the driver of car A 0.75 s to react (this is the normal reaction time for drivers). When he applies his brakes, he decelerates at 20 ft/s². (Figure 1) Part A Determine the minimum distance d between the cars so as to avoid a collision, Express your answer to three significant figures and include the appropriate units. • View Available Hint(s) d = 8.44 ft Submit Previous Answers Figure < 1 of 1> v Correct Here we learn how to find the minimum distance between the cars needed to avoid a collision in a situation when the front one suddenly starts to brake and the back one starts to brake more intensely after the reaction time passes.

How would you draw the kinematic diagram or free body diagram of this problem?

I Review Car B is traveling a distance d ahead of car A, Both cars are traveling at 60 ft/s when the driver of B suddenly applies the brakes, causing his car to decelerate at 12 ft/s?. It takes the driver of car A Part A 0.75 s to react (this is the normal reaction time for drivers). When he applies his brakes, he decelerates at 20 ft/s?. (Figure 1) Determine the minimum distance d between the cars so as to avoid a collision. Express your answer to three significant figures and include the appropriate units. • View Available Hint(s) d = 8.44 ft Submit Previous Answers Figure 1 of 1> Correct Here we learn how to find the minimum distance between the cars needed to avoid a collision in a situation when the front one suddenly starts to brake and the back one starts to brake more intensely after the reaction time passes.
