A wheel of radius 8.9 feet is moving forward at 11 feet per second. How fast is the wheel rotating?0.35 radians/sec0.81 radians/sec3.5 radians/sec1.2 radians/sec

Sagot :

The formula for velocity is

[tex]v=rw[/tex]

Where:

v = velocity

r = radius

w = wheel rotation

Therefore, we find the wheel rotation (w):

[tex]\begin{gathered} 11=8.9w \\ \frac{11}{8.9}=\frac{8.9w}{8.9} \\ w=1.23 \end{gathered}[/tex]

Answer: 1.2 rad/sec
