Work-Energy For Rotation And Rolling

Mark
< Prev
Next >

A wheel with mass MM, radius RR, and moment of inertia II is brought to rest by a constant frictional torque τ\tau at its axle in two scenarios. In the first, the wheel rotates about a fixed axle with an initial angular velocity of ω0\omega_0 and stops after covering an arc length of drotationd_{\text{rotation}}. In the second, the wheel rolls without slipping with an initial speed of v0=ω0Rv_0 = \omega_0 R and stops after traveling a distance of drollingd_{\text{rolling}}. Which equation correctly relates drollingd_{\text{rolling}} and drotationd_{\text{rotation}}?

A

drolling=drotationd_{\text{rolling}} = d_{\text{rotation}}

B

drolling=drotation⋅(1+IMR2)d_{\text{rolling}} = d_{\text{rotation}} \cdot \left(1 + \frac{I}{MR^2}\right)

C

drolling=drotation⋅(1+MR2I)d_{\text{rolling}} = d_{\text{rotation}} \cdot \left(1 + \frac{MR^2}{I}\right)

D

drolling=drotation⋅IMR2d_{\text{rolling}} = d_{\text{rotation}} \cdot \frac{I}{MR^2}
