Two cars travel the same distance 141 m. The first car travels this distance
with a constant speed of 88 m/s. The
second car starts from rest and covers
the same distance with a constant
acceleration of 15 m/s2. In the end one
of the cars cover this distance earlier;
how many seconds later does the other
car finish? Write your answer up to one
decimal place.

You are driving to the grocery store at 20 m/s. you are 110m from an intersection when the traffic light turns red. assume that your reaction time is 0.50s and that your car brakes with constant acceleration. how far are you from the intersection when you begin to apply the brakes? what acceleration will bring you to rest right at the intersection? how long does it take you to stop after the light changes? the known values: vi=20m/s xi=110m t=.50s vf=0m/s xf=0m a=?
