A boy kicked a ball at an angle 41 degrees with the horizontal. The ball reaches at the maximum height and then continues traveling until it hits the wall. The wall is 8.8 m away from the place where the boy kicked the ball, and the ball hits the wall 0.98 s after it was kicked. Air resistance is neglected. Set the upward direction as positive. Magnitude of the gravitational acceleration is 9.8 m/s. What is the initial velocity of the ball? What is the height of the ball relative to the ground where the ball hits the wall? What is the magnitude of velocity of the ball just before it hits the wall
