Solve the problem. Assume projectile is ideal, launch angle is measured from the horizontal, and launch is over a horizontal surface, unless stated otherwise.A fan in the bleachers at Wrigley Field throws an opposing player's home run back onto the playing field. Assume that the fan is 30 feet above the field and that the ball is launched at an angle of 33°. When will the ball hit the ground if its initial speed is 27 ft/sec?
