AI Thread Summary
A 75-kg person climbing a flight of stairs 10 m high does approximately 7357.5 joules of work, calculated using the formula W = (f)(d), where force is derived from the person's weight. The force is determined by multiplying mass (75 kg) by gravity (9.81 m/s²), resulting in 735.75 N. This force is then multiplied by the distance (10 m) to find the total work done. The correct answer is approximately 7350 J, confirming the calculations are accurate. Understanding that work is the product of force and distance is crucial in these physics problems.

How much work is done when a 75-kg person climbs a flight of stairs 10 m high at a constant speed

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

Your answer is correct. Work is just force acting over a distance. Here, the force is the weight of the person (force of gravity), and the distance is the height of the steps.
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
