A 15 kg box is sliding across the floor with a speed of 5.0 m/s. If friction brings it to a stop in 2.75 m, what is the work done by friction? What is the force of friction? What is the coefficient of friction?

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.

high-sugar diet and high cholesterol

c) power lifting, will be your answer.
