Sasha is driving straight and notices an antelope in the road a ways off. Determine the stopping distance (from the time she sees the antelope) for her car with an initial speed of 95 km/hr and an acceleration of -4.0 m/s2. Sasha's reaction time to start breaking is 1.0 second.

Answer 1

conversion:26.39 m/s
v=v(i)+at
v has to be zero because she is going to stop. initial is 26.39 m/s

0=26.39 m/s+(-4.0)t

solve for t and add then add 1 sec(reaction time).

Answer 2

but then
1 second * initial speed + (1/2)(4)t^2
