Achild is riding a ferris wheel with his stuffed bear. the wheel has a diameter of 12.0 m, and it rotates at a rate of 4.0 revolutions per minute. when exactly at the top of the ride the child accidentally drops the stuffed bear. assuming negligible air resistance, how far horizontally from the base of the ferris wheel does the bear land on the ground?

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
