Question
A body is rolling down an inclined plane. If kinetic energy of rotation is $40 \%$ of kinetic energy in translatory state, then the body is a(a) ring(b) cylinder(c) hollow ball(d) solid ball
Step 1
The angular velocity $\omega$ can be expressed as $\frac{v}{r}$, where $v$ is the linear velocity and $r$ is the radius of the body. Show more…

A body is rolling down an incline plane. If the rotational $\mathrm{K}$.E. of the body is $40 \%$ of its translational $\mathrm{K} . \mathrm{E}$. then the body is $\ldots$ $\{\mathrm{A}\}$ ring \{B\} Cylinder $\{\mathrm{C}\}$ solid sphere \{D\} hollow sphere
An object is rolling without slipping, with a translational kinetic energy of $K E_{\text {trans and a }}$ rotational kinetic energy of $K E_{\text {rot. }}$ If $K E_{\text {trans }} / K E_{\text {rot }}=3 / 2,$ what might this object be, a. a hoop, b. a spherical shell, c. a solid cylinder, or d. a solid sphere?
