A football is kicked from a point on the ground that is a horizontal distance d from the goalpost. For the attempt to be successful, the ball must clear the crossbar, 10 ft (about 3.05 m) above the ground. The ball leaves the kicker's foot with an initial speed of 20.0 m/s at an angle of 30.0∘ above the horizontal. Calculate the speed of travel of the football when it reaches the top of the goal.
