A boy throws a baseball onto a roof and it rolls back down and off the roof with a speed of 3.80 m/s. If the roof is pitched at 38.0° below the horizon and the roof edge is 3.70 m above the ground, find the time the baseball spends in the air and the horizontal distance from the roof edge to the point where the baseball lands on the ground.

a)the time the baseball spends in the air (in s)

b)the horizontal distance from the roof edge to the point where the baseball lands on the ground (in m)

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?
