Throws the ball horizontally with an initial velocity

Reference no: EM13677968

A boy sits in a window of his house, five meters above the ground. He wants to throw a ball to his friend on the lawn below him. After careful calculations, he throws the ball horizontally with an initial velocity of 12 m/s and the ball lands right at his friend’s feet. How far away is his friend from the house? Presume g = 10 m/s²
