1. The problem statement, all variables and given/known data The brakes on your car are capable of slowing down your car at a rate of 4.9 m/s^2. If you are going 132 km/h and suddenly see a state trooper, what is the minimum time in which you can get your car under the 90 km/h speed limit? 2. Relevant equations v(t)= at + initial velocity (final velocity^2) - (initial velocity^2) = 2*a*delta X (change in position) 3. The attempt at a solution I came out with 8.57 seconds. Is there some converting I maybe missed?
