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 11 m/s at an angle 44 degrees; with respect to the horizontal. Sarah catches the ball 1.5 meters above the ground.
-------------------------------------------------------------------------

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?

idku · Answer

I attempted (for question # 2)  $11\sin(44)\approx7.6$m/s    but it doesn't work when I enter it in my pracice thingy.
