    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 17 m/s at an angle 34 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 right before Sarah catches it? 2) what is the vertical component of the ball's velocity right before Sarah catches it? 3) what is the time the ball is in the air? 4) what is the distance between the two girls?

    I do suggest start with the easy one first - what is the horizontal velocity of the ball when it leaves Julie's hand? Does it change as the ball flies through the air? Post back with your attempt at this (and the other questions) and we'll help if you are still stuck.
