- A parent at a Little League game returns a foul ball by throwing it back onto the field. When the parent throws the ball back, she is standing and ends up releasing the ball from a point that is 2.50m above the ground. Your best guess is that she threw the ball upward at an angle of 60o with respect to the ground and it landed 13m away from her. What was the height of the ball's apex (as measured from the ground)?A soccer ball is kicked from ground level and sails over a horizontal field until it bounces off a vertical brick wall. The ball comes off the player's foot with a speed of 16.0m/s at an angle of 34.0∘ above horizontal. The ball strikes the wall when it is at a height of 3.00m from the ground. What is the horizontal distance between the wall and the initial position of the ball?Daily Commissions. Ganyu used her charged attack to shoot an arrow hitting a hilichurl tower a certain distance away from her.
