A wheel has angular acceleration of 3.0 rad / sec ^2 and an initial angular speed of 2~ rad / sec . In a time of 2 sec it has rotated through an angle (in radian) of:

Options

  1. A10
  2. B12
  3. C4
  4. D6

Correct answer

A. 10

Step-by-step solution

Here = t+ 1 2 t^2 aligned & =(2)(2)+ 1 2 (3)(2)^2 & =4+6=10 rad aligned
