A wheel has angular acceleration of 3.0rad/s23.0 \mathrm{rad} / \mathrm{s}^2 and an initial angular speed of 2.00rad/s2.00 \mathrm{rad} / \mathrm{s}. In a time of 2 s it has rotated through an angle (in radian) of

Options

  1. A6
  2. B10
  3. C12
  4. D4

Correct answer

B. 10

Step-by-step solution

θ=ω0t+12αt2\theta=\omega_0 t+\frac{1}{2} \alpha t^2 Given, α=3.0rad/s2,ω0=2.0rad/s,t=2 s\alpha=3.0 \mathrm{rad} / \mathrm{s}^2, \omega_0=2.0 \mathrm{rad} / \mathrm{s}, t=2 \mathrm{~s}. Hence, θ=2×2+12×3×(2)2\quad \theta=2 \times 2+\frac{1}{2} \times 3 \times(2)^2 or θ=4+6=10rad\theta=4+6=10 \mathrm{rad}
