You need to design an industrial turntable that is 56.0 cm in diameter and has a kinetic energy of 0.260 J when turning at 37.0 rpm (rev/min). Required:
a. What must be the moment of inertia of the turntable about the rotation axis?
b. If your workshop makes this turntable in the shape of a uniform solid disk, what must be its mass?

12 drag each label to the correct category. decide whether each statement describes mass or weight. measured in newtons measured in kilograms does not change when gravity changes === a gravitational force changes when gravity changes the amount of matter in something mass weight

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

Energy transformations that involve one transformation from one type of energy to another are called transformations.
