A student weighing 120 lbs climbs a 12 ft flight of stairs in 9 seconds. how much power did the student create?

Power can be calculate through the equation,

Power = Force x velocity

It should be noted that velocity is calculated by dividing displacement by time. Thus, from the given in this item we can calculate for the power.

Power = (120 lb) x (12 ft/9 s)

Power = 160 lb. ft/s
