Question

A girl weighing 500 Newtons takes 50 seconds to climb a flight of stairs 18 meters

high at a speed of 0.36 m/s. Her power output vertically is-

Answer 1

180Watts

Step-by-step explanation:

Power = Force * distance/Time

Given

Force = 500N

Distance = 18m

Time t = 50secs

Substitute into the formula

Power = 500*18/50

Power = 10 * 18

Power = 180Watts

Hence her power output vertically is is 180Watts
