Awheel with rotational inertia 0.04 kg. m 2 io and radius 0.02 m is turning at the rate of 10 revolutions per second when a frictional torque is applied to stop it. how much work is done by the torque in stopping the wheel?
(a) -0.0008 j
(b) -0.4tj
(c) -2 j c
(d) -22 j
(e) -82j

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

where is the photo and the answer choices?

statement #3 on andre"s list is false.
