NEET2009PhysicsRotational MotionActual
A wheel has angular acceleration of 3.0 rad / s ^2 and an initial angular speed of 2.00 rad / s . In a time of 2 s it has rotated through an angle (in radian) of
Options
- A6
- B10
- C12
- D4
Correct answer
B. 10
Step-by-step solution
= ₀ t+ 1 2 t^2 Given, =3.0 rad / s ^2, ₀=2.0 rad / s , t=2 ~s . Hence, =2 2+ 1 2 3 (2)^2 or =4+6=10 rad
