Determine the stopping distances for an automobile with an initial speed of 95km/h and human reaction time of 1.0s:

Question

(a) for an acceleration a= -5.2m/s^2

(b) for a= -6.7m/s^2

Answer 1

change speed to m/s

Vf^2=Vi^2+2ad solve for d.

Answer 2

oh yes, add distance Vi*.1 to each of those distances.....
