Projectile trajectories-urgent!

lundi 30 décembre 2013

1. The problem statement, all variables and given/known data



A construction worker stands in a 2.6m deep hole, 3.1m from the edge of the hole. He tosses the hammer to a person outside the hole. If the hammer leaves his hand 1m above the bottom of the hole at an angle of 35, what is the minimum speed needed to clear the edge.



2. Relevant equations







3. The attempt at a solution



Attachment 65211



Why does the book states the answer = 11m/s?



This is really frustrating!
