below horizontal
average height of a one-story building.Part A) Using the second equation of kinematics along with vertical motion
Solving the quadratic equation we get
Ignoring the negative value of the time we get
Part B) Horizontal velocity when she strikes the ground
Vertical velocity when she strikes the ground
the angle at which she strikes the ground.

A snowball rolls off a barn roof that slopes downward at an angle of 40 ?...
A snowball rolls off a barn roof that slopes downward at an
angle of 40 ? (Figure 1) . The edge of the roof is 14.0 m above the
ground, and the snowball has a speed of 7.00 m/s as it rolls off
the roof. Ignore air resistance.
Assume the coordinate origin is at the point on the roof where
the snowball rolls off and that the positive xdirection is
to the right and the positive y direction is upwards....
A solid cylinder of radius 10 cm and mass 13 kg starts from rest and rolls without slipping a distance of 6.0 m down a house roof that is inclined at 30°
A solid cylinder of radius 10 cm and mass 13 kg starts from rest and rolls without slipping a distance of 6.0 m down a house roof that is inclined at 30°. (See the figure.) What is the angular speed of the cylinder about its center as it leaves the house roof? The outside wall of the house is 5 m high. How far from the edge of the roof does the cylinder hit the level ground?
