The acceleration experienced by the particle is given by
This corresponds to the centripetal acceleration of the motion, which is related to the angular speed
of the particle and its distance r from the axis by the relationship
In our problem,
, so we can solve for
:
However, we must convert it into rpm (revolution per minute).
We know that 1 rad corresponds to
revolutions, while
. So we the conversion is
Answer:
A. Its translational kinetic energy is larger than its rotational kinetic energy.
Explanation:
Given that
Radius = R
Mass = M
We know that mass moment of inertia for the solid sphere
Lets take angular speed =ω
Linear speed =V
Condition for pure rolling , V= ω R
Rotation energy ,RE
RE= 0.2 MV²
The transnational kinetic energy TE
TE= 0.5 MV²
From above we can say that transnational energy is more than rotational energy.
Therefore the answer is A.
Well, an electromagnetic wave can pass through a vacuum of space and examples of that is lasers. so the correct answer is A.Lasers.
