Question

Jasper climbs a flight of stairs 0.63 minute at constant speed. if his mass is 65kg and the stairs is 12m high, what is the power output?
given? unknown? formula? solution and final answer?​

Answer 1

→Answer :

Calculating the force.

→Given

Mass (m) = 65 kg.

Acceleration due to gravity (a) = 9.8 m/s²

Force (F) = ?

F = ma

F = (65)(9.8)

F = 637 N

Calculating Power.

→Given

Force (F) = 637 N

Time (t) = 0.63 mins or 39.6 s

Distance (d) = 12 m

Power (P) = ?

P = Fd / t

P = (637)(12) / 39.6

P = 7644 / 39.6

P = 193.03 W
