1. The problem statement, all variables and given/known data The instant the traffic light turns green a car accelerats at 3.2 m/s^2. At the same instant a truck travelling at 20m/s overtakes the car. a) How far until the car overtakes the truck b)How fast is the car travelling when it overtakes the truck. 2. Relevant equations V1c=o VT=20.0 m/s D=? D=? a1=3.2m/s^2 t2=D/20 t1=? a=0 m/s^2 3. The attempt at a solution D1=V1t +1/2at^2 =0+1.6(D/20)^2 =(1.6D^2/400) The last part is where I am stuck. I dont know how to properly square a number/number.
