A garden hose shoots water horizontally from the top of a tall building toward the wall of a second
building 20 meters away. If the speed with which
the water leaves the hose is 5 m/sec, how long does
it take the water to reach the second building, and
what distance does the water fall in this time?

Astone is thrown with a speed v0 and returns to earth, as the drawing shows. ignore friction and air resistance, and consider the initial and final locations of the stone. which one of the following correctly describes the change δpe in the gravitational potential energy and the change δke in the kinetic energy of the stone as it moves from its initial to its final location? options a.δpe = 0 j and δke = 0 j b.δpe is positive and δke is negative c.δpe = 0 j and δke is positive d.δpe is negative and δke is positive e.δpe = 0 j and δke is negative
