Surfing For Reaction Distance Time?

George asks…Determine the stopping distances for a car with an initial speed of 97 km/h and human reaction time of 1.0 s,?1. Determine the stopping distances for a car with an initial speed of 97 km/h and human reaction time of 1.0 s, for an acceleration a = - 3.9m/s^2

2. Determine the stopping distances for a car with an initial speed of 97 km/h and human reaction time of 1.0 s, for an acceleration a = - 7.3 m/s^2Nancy answers:V(t) = at + v0
d(t) = 0.5 * at^2 + v0 * t + d0

(For these
