Asolid sphere with a moment of inertia of 2.20 kgm2 is rolling along the ground (without slipping) with an angular velocity of 15.1 rad/s . find (a) its rotational kinetic energy and (b) its translational kinetic energy.

Explanation:

It is given that,

Moment of inertia of a solid sphere,

Angular velocity of the solid sphere,

(a) The rotational kinetic energy of the solid sphere is given by :

(b) The translational kinetic energy of the solid sphere is given by :

Moment of inertia of solid sphere is :

Hence, this is required solution.

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
