(Solved): The angular displacement, \theta radians, of the spoke of a wheel is given by the expression \theta ...
The angular displacement,
\theta radians, of the spoke of a wheel is given by the expression
\theta =1.2t^(4)-t^(3), where
tis the time in seconds. a) The angular velocity after 2 seconds
(\omega _(2)).
\omega _(2)=,ra(d)/(sec)b) The angular acceleration
(\alpha _(4))after 4 seconds
\alpha _(4)=ra(d)/(sec^(2))c) The time when the angular acceleration is zero
(t_(0))in seconds.
t_(0)=
◻Round your answer to 2 decimal places.
