Determine the stopping location of the prize wheel. At this moment it is centered on the number 11. It is spinning at a rate of

Goshia [24]

Answer:

The wheel spins for 11.43s. The number cannot be determined.

Explanation:

We know that initial velocity is 124.4 rpm = 13.027137522 rad/s, acceleration is -1.14 rad/s^2, and final velocity is assumed to be 0 rad/s. We are asked to find t and displacement. We use the equation $\omega=\omega_0+\alpha t$ where $\omega=0 rad/s$ , $\omega_0=13.027 rad/s$ , $\alpha=-1.14rad/s^2$ , and $t=?$ .
