hey user !!!
mass of girl= 55kg
as she runs up a flight so motion energy is occured...
force =??
theirfore we know that force= mg
= 55×9.8
= 539 newton
now work done = force × displacement
= 539×0.15
= 80.85 joule
theirfore ,, the requried work done = 80.85 joule ...
plz mark my answer as brainliest
