d = 20(15) -(1/2)(2)(15^2)
= 300 - 225 = 75 m
150 - 75 = 75
a car moving on a straight road with a speed of 20m/s. at t=0 the driver of the car applies the breaks after watching an obstacle 150m ahead. after application of breaks, the car s with 2m/s^2. find the position of the car from the obstacle at t=15s.
