104in rotational kinetic energy is equals to 1 by 2 I w2 that is equals to 2 by 2 I what does w represent ​

I is the moment of inertia which is a scalar

w is the angular velocity

Explanation:

Kinetic energy has the Formula

           K = ½ m v²

if the system is rotating, the linear velocity is related to the angular velocity

          v = wr

we substitute

         K = ½ m w² r²

         K = ½ (m r²)  w²

If we consider the body as punctual

         I = m r²

we substitute

       K = ½ I w²

we can see that

I is the moment of inertia which is a scalar

w is the angular velocity

K is called the rotational kinetic energy

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
