AI Thread Summary
To determine the work done by a 100kg man climbing a 10m ladder, the equation W = mgh is used, where g is the acceleration due to gravity (approximately 9.81 m/s²). This results in a total work output of 9800 joules. To find the man's power output, the formula P = W/t is applied, where t is the time taken (12 seconds), yielding a power output of approximately 816.67 watts. The discussion emphasizes using the correct physics equations to solve for work and power. Overall, the calculations demonstrate the relationship between work, power, and time in physical activities.

Homework Statement


A 100kg man climbs a vertical 10m ladder in 12s.
How much work is done by the man?
What is the man's power output?


Homework Equations


For the work I think I need
W=F.s and F=(change in momentum)/time

I've got no idea what the equation for power is though.


The Attempt at a Solution


Work = force x 10

Use Eg = mgh to find how much work the man does.
Then use mikelepore's indicated site to calculate power.
 

Thread 'Rolling without slipping on a curved surface'

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 .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

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...
