centripetal acceleration
Not what you're looking for?
Shown from the top view are six blocks that are sitting at rest on rotating turntables. All of the turntables have the same rotation rate (i.e. same frequency). The masses of the blocks and how far out from the center they sit varies. The specific values are given in the figures.
Which of the following statements are true about the situations depicted in the figures above?
(Give ALL correct answers: B, AC, BCD.., or None )
A) The blocks in pictures A and B experience the same centripetal force
B) The linear (tangential) speed of the blocks in pictures A, B and F is the same
C) The period of rotation of the blocks is the same in pictures A, B and E
D) The net force on the blocks in pictures A and D is the same
E) The blocks in picture B and E experience the same centripetal acceleration

Solution Summary
Centripetal acceleration is considered.
Solution Preview
(A) The centripetal force is equal to "M R w^2", for A and B we have equal product of m and R therefore the forces are equal. TRUE
<br>(B) The tangential speed is "R w" which is different for A,B and F because they're at different radii. ...
