Question

Q.34 an annular disc has a mass m, inner radius r and outer radius 2r. The disc rolls on a flat surface without slipping. If the velocity of the center of mass is v, the kinetic energy of the disc is (a) 2 16 9 mv (b) 2 16 11 mv (c) 2 16 13 mv (d) 2 16 15 mv

Answer 1

Answer:

Hii mate

Explanation:

✒An annular disc has a mass m, inner radius R and outer radius 2R. The disc rolls on a flat surface without slipping. If the velocity of the centre of mass is v, the kinetic energy of the disc is: (-Gate

✒r 2 . The disc rolls on a flat surface without slipping. ... \frac{1}{ 2}mv^2+\frac{1 ... given, velocity of centre of mass is v ... 1/2 mv² + 5/16 mv²
