Answer:

1.16\:\mathrm{rad/s}

Step-by-step explanation:

Angular speed is given by \omega=\frac{\Delta \theta}{\Delta t}, where \Delta \theta is angle change in radians and \Delta t is elapsed time.

Since the baseball makes one fourth (one quarter) of a rotation in 1.35 seconds, it will take the baseball 4\cdot 1.35=5.4 seconds to complete on rotation.

One rotation is 360 degrees or 2\pi radians. Therefore, the angular speed of the baseball is:

\omega =\frac{2\pi}{5.4}=1.16355283466\approx \boxed{1.16\:\mathrm{rad/s}}
