Problem

Which of the following equations correctly relates the final angular velocity ωf\omega_f, the initial angular velocity ωi\omega_i, the constant angular acceleration α\alpha, and the angular displacement θ\theta for an object experiencing constant angular acceleration? a) ωf2=ωi2+α θ\omega_f^{2} = \omega_i^{2} + \alpha\,\theta b) ωf2=ωi2−2 α θ\omega_f^{2} = \omega_i^{2} - 2\,\alpha\,\theta c) ωf2=ωi2+2 α θ\omega_f^{2} = \omega_i^{2} + 2\,\alpha\,\theta d) ωf=ωi+α θ\omega_f = \omega_i + \alpha\,\theta
