Question
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 35 degrees; with respect to the horizontal. Sarah catches the ball 1.5 meters above the ground.
1.)What is the vertical component of the ball
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 35 degrees; with respect to the horizontal. Sarah catches the ball 1.5 meters above the ground. What is the vertical component of the ball's velocity right before Sarah catches it? What is the time the ball is in the air? How high above the ground will the ball be when it gets to Julie?Explanation / Answer
1. Vy= 17*sin(35)=-9.75 m/s , - sign due to down ward velocity
2. t=2*(Vy/g)=2*17*sin(35) /9.8=1.99 sec or 2 sec
