A Wheel Was Spinning At 28 Rads It Took 32 Seconds To Stop Completely What Is The Acceleration Of The Wheel class=

Sagot :

Given

The angular velocity is

[tex]\omega=2.8\text{ rad/s}[/tex]

The time taken,

[tex]t=3.2s[/tex]

To find

The acceleration of the wheel

Explanation

The acceleration is

[tex]\begin{gathered} \alpha=\frac{\omega}{t} \\ \Rightarrow\alpha=\frac{2.8}{3.2}=\frac{0.875rad}{s^2} \end{gathered}[/tex]

Conclusion

The acceleration is

[tex]0.875\text{ rad/s}^2[/tex]
