For a rigid body, the angular velocity of any particle about a given axis of rotation is:
- A.same for all particles✓
- B.different for different particles
- C.zero at the axis
- D.maximum at the axis
Explanation: In a rigid body, all particles have the same angular velocity about the axis of rotation.
Consider the following statements about the phases of long jump: 1) The athlete attains maximum momentum by running on the runway before take-off. 2) During take-off, the athlete pushes off with the weaker foot to maintain balance. Which of the statements given above are correct?
- A.Only 1 is Correct✓
- B.Only 2 is Correct
- C.1 and 2 are correct
- D.Neither 1 nor 2 are Correct
Explanation: Statement 1 is correct as maximum momentum is built by running, but statement 2 is incorrect as the athlete pushes off with the stronger foot.
