1. The problem statement, all variables and given/known data A plane starts from rest and accelerates in a straight line along the ground before takeoff. It moves 600m in 12s. Find a) acceleration, b) speed at the end of 12s, c) the distance moved during the twelfth second. 2. Relevant equations d = vot + 1/2at^2 v = vot + at 3. The attempt at a solution I got the answers to part a and b, but not to part c. I feel stupid, I've been staring at this part for awhile. Things are not registering... Do i use the first equation? someone please help!
