Chapter 3. 8) A football kicker can give the ball an initial speed of v . Within what two elevation angles must he kick the ball to score a field goal from a point at a distance L to the front of goalposts whose horizontal bars is at a height h above the ground? (Hint use 1 sin cos 2 2 = + θ to get a relation between 2 tan and 2 cos 1 , substitute, and then solve the quadratic equation) v r a r...
