The parallel axis theorem provides a useful way to calculate the moment of inertia i about an arbitrary axis. the theorem states that i = icm + mh2, where icm is the moment of inertia of the object relative to an axis that passes through the center of mass and is parallel to the axis of interest, m is the total mass of the object, and h is the perpendicular distance between the two axes. use this theorem and information to determine the moment of inertia (kg·m2) of a solid cylinder of mass m = 1.40 kg and radius r = 3.20 m relative to an axis that lies on the surface of the cylinder and is perpendicular to the circular ends.

i think the answer is a, hope this : )

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
