Alarge building has an inclined roof. the length of the roof is 54.0 m and the angle of the roof is 17.0° below horizontal. a worker on the roof goes 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 2.87 m/s2. after leaving the edge of the roof, it falls a vertical distance of 46.5 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?
b. how far horizontally does the hammer travel from the edge of the roof until it hits the ground?
