Baseball and the Washington Monument On August 25, 1894, Chicago catcher William Schriver caught a baseball thrown from the top of the Washington Monument (555 , 898 steps).
A.) If the ball was thrown horizontally with a speed of 7.50 m/s , where did it land? answer in meters
B.) What was the ball's speed of motion when caught? answer in m/s
C.) What was the ball's direction of motion when caught? answer in degree
