Calculate the mechanical advantage of a ramp if the box you are trying to move has a mass of 10 kilograms, the board is 15 feet long and the height of the ramp is 5 feet. A. 300 B. 45 C. 3 D. 150

thermal energy is the answer

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.

a sonic boom is a loud boom that breaks the sound barrier
