Rotational Kinematics & Dynamics

A wheel has angular acceleration of 3.0 rad/sec2 and an initial angular speed of 2.00 rad/sec. In a time of 2 sec it has rotated through an angle (in radian) of

Show answer and solution

Answer: (a)

  1. θ=ω0t+12αt2\theta = \omega_0 t + \frac{1}{2}\alpha t^2
  2. θ=2×2+12×3×22=4+6=10\theta = 2 \times 2 + \frac{1}{2} \times 3 \times 2^2 = 4 + 6 = 10 rad
  3. So the answer is (a) 10.
