What am I doing wrong?
Posted September 3, 2015
When you're solving for Vfy, recall that we called down the positive direction. Therefore, the square root that you want is the positive root (we know the ball is moving down), so vfy=+4.75 m/s, indicating it's moving downward at 4.75 m/s. (You'll find the rest of the solution on the next page of the book). Hope that helps!
