HELP PLEASE A 51.7 kg hiker that ascends a 43.2 m hill at a constant speed of 1.20 m/s. It takes the hiker 384 seconds to reach the top. On the journey the hikers potential energy is___
The total change in gravitational potential energy for the hiker is The amour if work done by the hiker to reach the top of the hill is___
The hiker requires watts of power to get to the top of the hill in 384 seconds

answer: 0.20

explanation: this can only be the answew because all the other measuremnets are not close

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.
