An object of mass m has angular acceleration alpha =0.2" rad s"^(-2). What is the angular displacement covered by the object after 3 second ? (Assume that the object started with angle zero with angular velocity).

An object of mass m has angular acceleration alpha =0.2" rad s"^(-2).

1.	An object of mass m has angular acceleration alpha =0.2" rad s"^(-2). What is the angular displacement covered by the object after 3 second ? (Assume that the object started with angle zero with angular velocity).
Answer» Solution :`THETA=omega_(0)t+(1)/(2)ALPHAT^(2)` `theta=(1)/(2)xx0.2xx3^(2)=0.9` rad (or) `51^(@)54`
