A 84.7 kg refrigerator rests on the floor. How much work is required to move it at constant speed for 2.25 m along the floor against a friction force of 193.5 N

prolly a beacuse the momentuem the car has increases while going down hill

a straight line sloped

this could be newton#'s law of cooling. the cooling curve is exponential

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.
