Help me please Thank you

I\J \;y_# A large building has an inclined roof. The length of the roof lS 69.0 m and the angle of the roof is 24.0 below horizontal. A worker on the roof lets go of a hammer from the peak of the roof. Starting from rest, it slides down the entire length of the roof with a constant acceleration of 3.99 m/sz. After leaving the edge of the roof, it Falls a vertical distance of 21.5 m before hitting the ground. (a) How much time does it take the hammer to fall from the edge of the roof to the ground? X Given the acceleration of the hammer as It slides on the roof, what are the velocity components Just as it leaves the roof? How can you use these velocity components to nd the time it takes to fall from the roof to the ground? What Constant acceleration relations will you need? 5 (b) How far horizontally does the hammer travel from the edge of the roof until it his the ground? :J m A damnmn naval
