Question

a solid sphere mass 10kg having radius 20 cm roles on horizontal surface at the rate 20 radian per/sec find its total kintic energy​

Answer 1

Answer:

112J

Explanation:

For, a rolling body, total kinetic energy =Energy due to translatory motion+ Energy due to rotational motion

or, E = 0.5m(v)^2 + 0.5I(w)^2
