MCQ
A wheel is rotating with angular velocity $2 rad / s$. It is subjected to a uniform angular acceleration $2 rad / s ^2$ then the angular velocity after $10 s$ is
  • A
    12 rad/s
  • B
    20 rad/s
  • ✓
    22 rad/s
  • D
    120 rad/s
✓

Answer

Correct option: C.
22 rad/s
22 rad/s
$ω = ω_0+ αt$
Here $ω_0= 2 $ rad/s,
α = 2 rad/s2
ω = 10 s
ω = 2 + 2 x 10 = 22 rad/s
