Julie throws a ball to her friend Sarah. The ball leaves Julie's hand a distance 1.5 meters above the ground with an initial speed of 18.0 m/s at an angle 41.0 degrees; with respect to the horizontal. Sarah catches the ball 1.5 meters above the ground. 1) What is the horizontal component of the ball's velocity when it leaves Julie's hand?the the correct answer is 13.58 2) What is the vertical component of the ball's velocity when it leaves Julie's hand? the correct answer is 11.8 3) What is the maximum height the ball goes above the ground? 4) What is the distance between the two girls? 5) After catching the ball, Sarah throws it back to Julie. The ball leaves Sarah's hand a distance 1.5 meters above the ground, and is moving with a speed of 15.0 m/s when it reaches a maximum height of 10.0 m above the ground. What is the speed of the ball when it leaves Sarah's hand? 6) How high above the ground will the ball be when it gets to Julie?
