A turntable is rotating at a at a constant angular speed of
36 revolutions per minute. The radius of the turntable is
10 centimeters. A 0.30-gram bug starts walking slowly from the
center toward the rim of the turntable. The coefficient of static
friction between the bug and the turntable is 0.116.
(a) Find the magnitude of the force of static friction.
(b) Find the maximum distance in centimeters from the center of
the turntable that the bug can walk without slipping.

A2k pendulum has a speed of 1 m/s at a height of 1/2 meter

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.

Aplayground merry-go-round has a radius of 4.6 m and a moment of inertia of 200 kg-m2 and turns with negligible friction about a vertical axle through its center. a child applies a 26.0 n force tangentially to the edge of the merry-go-round for 15.0 seconds. if the merry-go-round is initially at rest, how much work did the child do on the merry-go-round?
