Question asked by Filo student

by $\vec{r}=\hat{i}+2\hat{j}-\hat{k}$ : 177 by: $\vec{p}=3\hat{i}+4\hat{j}-2\hat{k}$ Combined Translational and Rotational Motion 59. A body is rolling down an inclined plane without slipping. How does the acceleration of the rolling body depend on its radius? (a) It is inversely proportional to the square root of radius (b) It is directly proportional to the square root of radius of its present-day (c) It does not depend upon radius approximately: (d) It is directly proportional to the radius 60. A disc of radius $r$ rolls on a horizontal ground with linear acceleration a and angular acceleration $\alpha$ as shown in figure. The magnitude of acceleration of tating freely with point $\mathrm{P}$ shown in figure at an instant when its linear non-rotating dise velocity is $v$ and angular velocity is $\omega$ will be:
