2.A girl of mass 50kg climbs a flight of a stair having 40steps each of 30m high in 10 s. Calculate the power developed by the girl.​

Respuesta :

Answer:

[tex]{ \boxed{ \pmb{power = \frac{force \times distance}{time} }}} \\ [/tex]

  • force → (50 × 10) = 500 N
  • distance → (30 × 40) = 1200 m
  • time → 10 seconds

[tex]{ \rm{power = \frac{500 \times 1200}{10} }} \\ \\ { \rm{power = \frac{600000}{10} }} \\ \\{ \underline{ \underline{ \rm{ \dashrightarrow \: \: power = 60,000 \: newtons \: \: }}}}[/tex]
