vo Jewell threw a ball into the air in the direction of a wall that was a distance d = 8.4 meters in front of her. The ball left her hands a distance of h 1.7 meters above the ground. The ball left her hands with an initial speed of 19 meters per second, aimed at a direction of theta = 79 degrees above horizontal. To solve this problem, let g = 9.8 meters per second squared. Ignore air resistance %3D and other sources of friction. How high above the ground (measured in meters) did the ball hit the wall?
