A worker stands on the roof of a 45.0 m high building that is under construction. He throws a bag of debris giving it an initial velocity of 12.0 m/s at an angle of 33.0 ∘ from downward direction. How long is the bag in flight? How far from the building does the bag land? What is the bag's final speed just before it hits the ground?

A large building has an inclined roof. The length of the roof is 56.5 m and the angle of the roof is 17.0° 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 2.87 m/s2. After leaving the edge of the roof, it falls a vertical distance of 22.5 m before hitting the ground. (a)How...

A snowball rolls off a barn roof that slopes downward at an angle of α= 45.0∘ . (See the figure below) The edge of the roof is H= 17.0 m above the ground, and the snowball has a speed of v = 4.00 m/s as it rolls off the roof. Ignore air resistance. How far from the edge of the barn does the snowball strike the ground if it doesn't strike anything else while falling?
