Problem: The Bengals are in desperate need of a field goal. The ball is placed 40 yards from the goal posts, whose cross bar is 10 feet off the ground. If the ball is kicked from ground level at an initial angle of 350 above the horizontal,
Part A: What is the minimum initial speed that the ball must have to insure that it passes over the cross bar?
Part B: How much time does it take the ball to reach the cross bar after the kick?
I need help to find the minimum initial speed that the ball must have to insure that it passes over the cross bar.
