During a 6.0-s time interval. a flywheel with a constant angular acceleration turns through 500 radians that acquire anangular velocity of 100 rad/s. (a) what is the angular velocity at the beginning of the 6.0 s? (b) what is the angularacceleration of the flywheel?

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
