A block is sitting on a rotating turntable, and it is not slipping. If the turntable is rotating with a constant angular velocity, which of the following statements is true about the block? You might find it helpful to draw a picture of this situation.
a) Its acceleration is parallel to its velocity.
b) Its acceleration is perpendicular to its velocity.
c) The angle between the directions of its acceleration and its velocity is 45 degrees
d) Its acceleration is zero
Homework Answers
Take an example of a stone tied on the end of a string and is being rotated at constant angular velocity.
We have to apply a Force to keep this in motion, and there is a corresponding acceleration which is directed towards the centre of the Pivot ( fixed point).
When the string breaks, the stone moves tangent to the motion ( or the breaking point). This shows that the velocity of a Circular Motion is at the tangent at the point ( here the block).
Option (B) is correct
Note that since it is moving with constant velocity, there is no acceleration in tangential direction

A heavy turntable, used for rotating large objects, is a solid cylindrical wheel that can rotate about its central axle with negligible friction. The radius of the wheel is 0.330 m. A constant tangential force of 200 N applied to its edge causes the wheel to have an angular acceleration of 0.896 rad/s2. (a) What is the moment of inertia of the wheel (in kg ·m2)? kg · m2 (b) What is the mass (in kg) of the wheel? kg...
