FizziksGuy Posted September 3, 2015 Share 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! Quote Link to comment Share on other sites More sharing options...
