During the “Power Lab”, Andrew runs up the stairs, elevating his 79.5 kg body a vertical distance of 2.29 meters in a time of 1.32 seconds. Calculate the power generated by Andrew. (g = 9.8 m/s2)

second mirror gathers light from a faraway object and reflects it to another mirror. - a.

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.
