Question

A body rotating with uniform acceleration about its geometrical axis makes 8 rotations in the first 2 seconds. The number of rotations the body makes in the next 3 seconds is (Initially the body is at rest):

• A. 50
• B. 25
• C. 42
• D. 21

Hint:

For rotational motion with uniform acceleration, use the standard kinematic equations to calculate the number of rotations.

Answer 1

The Correct Option is C

Using the equations of rotational motion with uniform acceleration, we calculate the total number of rotations in the next 3 seconds. The result is 42 rotations. Thus, the correct answer is option (3).
