What is the acceleration of a piece of dust on an old-fashioned record album, 0.55 m from the center, if the record is spinning at 45 rpm (rotations/minute)? a. 5.82 m/s2
b. 3.35 m/s2
c. 4.68 m/s2
d. 12.3 m/s2

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.
