Car B is traveling a distance d ahead of car A. Both cars are raveling at 60 ft/s when the driver of B suddenly applies the mrakes, causing his car to decelerate at 12 ft/s² . It takes the triver of car A 0.75 s to react (this is the normal reaction time for trivers). When he applies his brakes, he decelerates at 14 ft/s (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. Valu Iuita

Measuring is the comparison of a particular physical quantity with its reference value. A unit is a fixed physical quantity. The length is a physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.
