anonymous 3 years ago 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 12.0 m/s at an angle 47.0 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? 2) What is the vertical component of the ball’s velocity when it leaves Julie's hand?

Using Trig Identities, $Sin(47)=\frac{V_{0y}}{12m/s}$ $12sin(47)=V_{0y}$ i'm sure you can do the second part =]

actually this is the second part you need the 1st part now =]
