How much work is done when a 75-kg person climbs a flight of stairs 10 m high at a constant speed(adsbygoogle = window.adsbygoogle || []).push({});

A.) 7.35 * 10^5 j

B.) 750 j

c.) 75 j

D.) 7500 j

E.) 7350 J

W = (f)(d)

f = ma

W= (ma)(d)

Now I'm assuming that the force is parallel to the stairs (distance as the person walks up the stairs)

so I found the force

f = ma

f= (75)(9.81) = 735.75

then I solved for work

W = (f)(d)

W = 735.75(10)

W = 7357.5 j

answer E

I'm new to to work so I just want to clarify if I'm doing the problem right or wrong

If I made any errors please feel free to correct me

We learn by our mistakes after all

Thank You
