What is the average power output of an athlete who can life 9.0 * 10^2 kg 2.5 m in 2.0 s?

Average power output of athlete = 11025 Watts

Explanation:

Work done is defined as the product of force applied and the displacement perpendicular to the force.

Work =

Power is defined as work done per unit time.

Power =

Here the person lifts 900 kg.

Height = 2.5 m

Time interval = 2 seconds

Force =

          =

          = 8820 N

Work done =

                   =

                   = 22050 J

Power =

           = 11025 Watt

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.
