Asked by vanessa

a driver in a car traveling at a speed of 21.8 m/s sees a cat 101m away on the road. How long will it take for the car to accelarate uniformly to a stop in exactly 99m?
Answered by MathMate
Use
v²-u²=2aS
where S=distance, 99m
a=acceleration to be found
v=final velocity, 0 m/s
u=initial velocity, 21.8 m/s
Solve for a.
