Three balls labelled 1, 2, and 3 fly off of the Leaning Tower of Pisa with the trajectories shown below. Ball 1 is launched horizontally from the top floor which is 40m, above the ground, while ball 2 is launched horizontally from the middle floor which is 20m, above the ground. Ball 3 is dropped from the middle floor. We can ignore air resistance. Rank air time

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.

i believe the answer is electric potential.

explanation:

amplitude

hope this
