Embibe Experts Solutions for Exercise 12: EXERCISE 6.12

On reaching by pure rolling at the bottom of incline the fraction of $\mathrm{KE}$ in rotational motion is $\frac{2}{5}$. Then the objects is perhaps

A particle performs uniform circular motion with an angular momentum $L$. If the frequency of particle motion is doubled and its kinetic energy is halved, the angular momentum becomes,

A particle $\left(5\mathrm{kg}\right)$ moves upon straight line with constant velocity $2 \mathrm{m} {\mathrm{s}}^{-1}$ along the straight line $2y=3x+4$. The angular momentum of particle about origin, in $\mathrm{kg} {\mathrm{m}}^2 {\mathrm{s}}^{-1}$ will be
