You're driving down the highway at 20m/s when you see a dog you don't want to crush it 35 m in front of you. Your reaction time before stepping on the brakes is 0.5s, and acceleration created by your brakes is 10 m/s^2 what was the distance travelled before coming to a stop?

Answer 1

did that just below.

Answer 2

S = ut + at*2/2

s= 20 * 0.5 + 10(0.5)*2

s= 10 + (10 * .25) /2
S = 10 + 1.25
S = 11.25 Meters
