## Homework Statement

it is a multi part problem i found most just need help on last two but gave answers to the ones i found because they are needed to determin the answer.

What is the translational kinetic energy of the real system, at the instant shown in the right diagram?

Ktrans = 10.412 J

What is the distance through which the gravitational force acts on the real system? .19 m

How much work is done on the system by the gravitational force?

Wgrav = -16.758 J

What is the distance through which your hand moves? .72 m

How much work do you do on the real system?

Whand = 102.96 J

At the instant shown in the right diagram, what is the total kinetic energy of the real system?

Ktotal = J

What is the rotational kinetic energy of the machinery inside the box?

Krot,f = J

## Homework Equations

from a question earlier on my assingment i found that only

translational and rotational kenetic energy are pressent

will need conservation of energy

delta(E) = W + Q

i assumed Q = 0 because we have not went in depth about heat trasfer due to friction and all that stuff.
