QUESTION:

Determine the kinetic energy of the 100-kg object.

ANSWER:

Problem P18-1

Determine the kinetic energy of the 100-kg object.

Step by Step Solution

Step 1 of 6

In the case of part (a) , the kinetic energy can be computed according to equation 1. In this occasion there is only rotational kinetic energy, and we only need to consider the moment of inertia about the pivot point O, which happens to be the same as the center of mass. Note that we have considered that the disk has a radius of 2 meters.
