The formula for the rotational kinetic energy is
where I is the moment of inertia. This is just mass times the square of the perpendicular distance to the axis of rotation. In other words, the radius of the propeller or this is equivalent to the length of the rod. ω is the angular velocity. We determine I and ω first.
ω = 573 rev/min * (2π rad/rev) * (1 min/60 s) = 60 rad/s
Then,

Answer:
The kinetic energy is
Explanation:
From the question we are told that
The potential difference is
The potential energy of the end is mathematically represented as
q is the charge on an electron with a constant value of
substituting values
Now from the law of energy conservation
The
Where is the potential energy at the end
So
The negative sign is not includes because kinetic energy can not be negative
