In a ball is thrown leftward from the left edge of the roof, at height h above the ground. The ball hits the ground 1.50 s later, at distance d = 25.0 m from the building and at angle theta=60.0^(@) with the horizontal. (a) Find h. (Hint: One way is to reverse the motion, as if on video.) What are the (b) magnitude and ( c) angle relative to the horizontal of the velocity at which the ball is thrown? (d) Is the angle above or below the horizontal? |
