47) Dr, Sachiko McBride takes an air balloon ride with her squirrel, named Hikaru. The air balloon is moving straight upward direction at 4.9 m/s of velocity. Now Hikaru throws a ball in horizontal direction at 12 m/s of velocity, and the ball hits the ground 5.0 seconds after it was thrown in the air. Set the upward direction as positive, Magnitude of the gravitational acceleration is 9,8 m/s?. Air resistance is neglected. (A) What was the height of the air balloon relative to the ground when Hikaru thrown the ball? (B) Find the distance along the x-axis from the starting point to where the ball hit the ground. (C) Find the maximum height that the ball reaches. (D) How much time does it for the ball take to reach at 77 m height from the ground
