Answer:
754.3 m
Explanation:
The moment of inertia of the solid disk:

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

The angular kinetic energy of the disk is then:

By law of energy conservation, this energy is converted to potential energy to pick up the 3kg block
let g = 9.8 m/s2

where
= 3 kg is the mass of block


ANS : 313℃
You need to use K in this.
To convert ℃ to Kelvin (K), add 273.15 to ℃.
Answer:270joules
Explanation:KE = 1/2mv^2
KE = 1/2(60kg)(3.0)^2 = 270 Joules
