Why do you think it is so important that all evidence be identified (such as marking the bullets and tagging firearms)? What con

sequences might result if these procedures were not followed?

A solid disk has a mass of 162 kg and a radius of 1.30m. This

RideAnS [48]

Answer:

754.3 m

Explanation:

The moment of inertia of the solid disk:

$I = mR^2/2$

Where m is the disk mass and R is the radius of the disk.

$I = 162*1.3^2/2 = 136.89 kgm^2$

The angular kinetic energy of the disk is then:

$E_k = I\omega^2/2 = 136.89 * 18^2/2 = 22176.18 J$

By law of energy conservation, this energy is converted to potential energy to pick up the 3kg block

let g = 9.8 m/s2

$E_p = m_bgh = 22176.18 J$

where $m_b$ = 3 kg is the mass of block

$3*9.8h = 22176.18$

$h = \frac{22176.18}{3*9.8} = 754.3 m$
