14. On a distant asteroid, a large catapult is used to throw chunks of stone into space. Could such a device be used as a propulsion sys-
tem to move the asteroid closer to the earth? Explain.

the reason is because the moon has some form of gravity, and that gravity pulls the ocean tides.

neither accurate nor precise.

c. magnitude and direction

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.
