Of the following situations, which one is impossible?
A. A body having zero angular velocity and non-zero angular acceleration.
B. A body having constant angular acceleration and variable angular velocity.
C. A body having angular velocity east and angular acceleration west.
D. A body having angular velocity east and angular acceleration east.
E. A body having constant angular velocity and variable angular acceleration.
Homework Answers
A body can't have constant angular velocity and variable angular acceleration.
Hence option E is the answer.
A is possible if a body is moving clockwise and its angular acceleration is in counterclockwise. After some time the angular velocity of the body will be zero at a moment in time.
B is possible constant angular acceleration changes the angular velocity.
C and D are possible as well with the axis of rotation along. east-west
