a) $\theta=2200rad$ b) $\theta=2800rad$ c) $\theta=2500rad$

Work Step by Step

We have: Initial velocity $\omega_0=+220rad/s$, final speed $\omega=+280rad/s$ and time $t=10s$ a) The engine's angular displacement if $\omega=+220rad/s$ is $$\theta=\omega_0\times t=2200rad$$ b) The engine's angular displacement if $\omega=+280rad/s$ is $$\theta=\omega_0\times t=2800rad$$ c) The actual displacement is $$\theta=\Big(\frac{\omega+\omega_0}{2}\Big)t=2500rad$$
