The following data resulted from a study taken on a horizontal milling machine: pieces produced per cycle: 8 average measured cycle time: 8.36 min average measured effort time per cycle: 4.62 min average rapid traverse time: 0.08 min average cutting time power feed: 3.66 min performance rating: 115 percent allowance (machine time): 10 percent allowance (effort time): 15 percent the operator works on the job a full 8-h day and produces 380 pieces. how many standard hours does the operator earn? what is the operator’s efficiency for the 8-h day?

the force on the thing and the distance the force moves the thing

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.
