Answer:[tex]\alpha =30-4=26 rad/s^2[/tex]
Explanation:
Given
Position of a car is given by
[tex]\theta =t^3-2t^2-4t+10[/tex]
and angular speed is [tex]\frac{\mathrm{d} \theta }{\mathrm{d} t}=\omega [/tex]
angular acceleration is
[tex]\frac{\mathrm{d^2} \theta }{\mathrm{d} t^2}=\alpha [/tex]
[tex]\alpha =6t-4[/tex]
at [tex]t=5 s[/tex]
[tex]\alpha =30-4=26 rad/s^2[/tex]
