Julie throws a ball to her friend Sarah. The ball leaves Julie'shand a distance 1.5 meters above the ground with an initial speedof 10 m/s at an angle 37 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 rightbefore Sarah catches it?
m/s
2)What is the vertical component of the ball’s velocity rightbefore Sarah catches it?
m/s
3)What is the time the ball is in the air?
s
4)What is the distance between the two girls?
m
5)After catching the ball, Sarah throws it back to Julie.However, Sarah throws it too hard so it is over Julie's head whenit reaches Julie's horizontal position. Assume the ball leavesSarah's hand a distance 1.5 meters above the ground, reaches amaximum height of 5 m above the ground, and takes 0.891 s to getdirectly over Julie's head.
