Answer: Mass is the quantity of matter in an object whereas weight is the force of gravity on an object.
Weight is dependent on gravity while mass is independent on gravity
Explanation:
I think the situation is modeled by the scenario in the attached image. Some specific values seem to be missing (like the height of door
)...
The door forms a right triangles that satisfies

We also have

so if you happen to know the height of the door, you can solve for
and
.
is fixed, so

We can solve for the angular velocity
:

At the point when
and
ft/s, we get

Should be 250m. check with your teacher and let me know
If he is jumping you are adding force which means that you will be falling twice as fast
