A wheel having a diameter of 3 m starts from rest and accelerates uniformly to an angular velocity of 210 r.p.m. in 5 seconds. Angular acceleration of the wheel is -
- 4.4 \(\frac{\mathrm{rad}}{\mathrm{~s}^{2}}\)
- 3.3\(\frac{\mathrm{rad}}{\mathrm{~s}^{2}}\)
- 2.2 \(\frac{\mathrm{rad}}{\mathrm{~s}^{2}}\)
- 1.1 \(\frac{\mathrm{rad}}{\mathrm{~s}^{2}}\)
Answer
(A) 4.4 rad ~s ^ 2
