1.	A wheel has angular acceleration of 3" rad/s"^(2) and initial angular speed of 2.00 rad/s. In a time 2 sec. it has rotated through an angle……….rad of :
Answer» 10 12 4 6 Solution :Equation for constant acceleration in rotation motion `theta=omega_(0)t+(1)/(2)alphat^(2)` Here initial angular SPEED `omega_(0)=2" RAD/s"` Angular acceleration `alpha=3` rad/s and time `t=2` `theta=(2xx2)+(1)/(2)(3)(2)^(2)` `=4+(1)/(2)xx3xx4` `therefore theta=10` rad
