A 12kg box of fruit needs to be moved to the other side of the warehouse. (a) Calculate the minimum force required to get the box moving if Ms = 0.47? (b) If the force from (a) is constant and continues to push the box,
how fast will the box accelerate if ux=0.33?

d. platinum would have the greatest temperature increase because it has the lowest specific heat.

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.
