Question

A man is weighed 450N runs up a flight of

Staires consisting of 25 steps each 10cm height
20s calculate the power

Answer 1

56.25 watts

Step-by-step explanation:

P = F * d / t

P = Power (it's an unknown at this point).

F = 450 N

d = 25 steps each 10 cm = 25 steps 0.1 m/step = 2.5 m

t = 20 s

Solution

P = 450 * 2.5 / 20

P = 1125/20

P = 56.25
