From the roof of a tall building, a boy throws a ball of mass m=700 g with initial speed v0 = 33.4 meter per second at an angle θ=27.8° below the horizontal. The ball is thrown from a height H above the ground. The boy measures the ball to be in the air for 4.19 second before it strikes the ground below. Obtain how far away from the building does the ball land? Neglect air resistance.
