Answer:
a)ωi = 66.66 rad/s
b)α =5.55 rad/s²
Explanation:
Given that
t= 6 s
θ = 500 rad
ωf= 100 rad/s
Lets take initial angular speed = ωi
If angular acceleration is constant
Lets take angular acceleration = α rad/s²
ωf=ωi + α t
θ = ωi .t+ 0.5 α t²
[tex]\theta =\dfrac{\omega_i+\omega_f}{2}\times t[/tex]
[tex]500=\dfrac{\omega_i+100}{2}\times 6[/tex]
ωi = 66.66 rad/s
ωf=ωi + α t
100=66.66+ α x 6
α =5.55 rad/s²
