A bicycle wheel has a mass of 1.0 kg, a radius of 0.35 m, and a rotational inertia of 0.1225 kg-m². The wheel is spun up to a rotational velocity of 6 radians per second and then placed on the ground and released, allowing it to roll away. Assuming no energy is lost to internal energy in this process, draw an energy bar chart for this process and use it to determine the linear and rotational velocity of the wheel once it is released.

Question
3) A bicycle wheel has a mass of 1.0 kg, a radius of 0.35 m, and a rotational inertia of
0.1225 kg-m². The wheel is spun up to a rotational velocity of 6 radians per second
and then placed on the ground and released, allowing it to roll away. Assuming no
energy is lost to internal energy in this process, draw an energy bar chart for this
process and use it to determine the linear and rotational velocity of the wheel once it
is released.
Ability A4: Is able to use representations other than math/words to solve problems
Needs Work
Inadequate
Adequate
All relevant representations
were used correctly to solve
the problem and the ways
they were used are clearly
explained.
Adequate
Bar chart is properly
labeled and has energy
bars of appropriate
magnitudes. The system is
clearly identified.
All relevant representations
were used to solve the
problems, but minor errors
were made or details of how
they were used are omitted.
Not all relevant
representations were used
or representations were
used incorrectly to solve the
problem.
Ability A8: Is able to construct an energy bar chart
Needs Work
Bar chart has the energy
bars drawn correctly, but
some labels are missing or
the system is not identified.
The bar chart matches the
process described with
some other representation.
Inadequate
Bar chart is either missing
energy values, bars drawn
do not show the
conservation of energy or
are drawn in the wrong
places. Bars could also be
labeled incorrectly. The
system is not identified.
Missing
Representations beyond
math/words may be present
but were not used to the
solve of the problem.
Missing
No representation is
constructed.
