A rookie quarterback throws a football with an initial upward velocity component of 16.5 and a horizontal velocity component of 18.3 . Ignore air resistance. A)How much time is required for the football to reach the highest point of the trajectory? I got 1.68s which is correct B) How high is this point? I can't get the right answer. I got 16.9m by doing: 0m+18.3(1.68)+1/2(-9.8)(1.68)2 Help please!
