Question

If you are driving at 50 miles an hour and slam on the brakes you will skid twice as far as if you were driving 25 miles per hour o you will skid four times as far as if you were driving 25 miles per hour O you will skid half as far as if you were driving 25 miles per hour O you will skid one quarter as far as if you were driving 25 miles per hour O you will skid the same distance as if you were driving 25 miles per hour

Answer 1

Option B is correct

You will skid 4 times

V_i = 50 m p h V_f = 0 d = (50)^2/2 a If V_i = 25 m p h d prime = (25)^2/2 a d/d prime = (50)^2/(25)^2 = 4 times
