Question

I need help finding the kinetic energies (reupload)

Answer 1

18.51 J

Step-by-step explanation:

First, we need to find the Kinetic energy of the disk. Since the disk travels in a straight line, we can use the formula
`K=(1)/(2)mv^2`:

`Kdisk=(1)/(2) 0.033*33.5^2\\Kdisk=18.51 J`

Since no other force is present, no friction, sound, or vibration, energy must be conserved. Therefore, the answer for both is 18.51 J.
