+60 A ball is thrown at 40 degrees above the horizontal. The ball is in the air for 7.2 seconds before it hits. If it travels 47.0 meters before it hits the ground, what was the initial velocity of the ball?
Which kinematic equations are needed to find the horazontal and vertical components of the initial velocity?
