Asked by Mitch
A crazy young woman on a motorcycle is cruising at 45 m/s down the expressway. Realizing the error in her ways, she slows down and stops her bike over a distance of 95m. Assuming it is constant, what was her acceleration?

v = average speed during stop = 45/2 = 22.5
95 = 22.5 t
v = Vi + a t
0 = 45 + a t
a = -45/t
95 = 22.5 t
v = Vi + a t
0 = 45 + a t
a = -45/t
