AI Thread Summary
When pushing a 25 kg box across a wooden floor at constant speed, the force exerted on the floor can be calculated using the coefficient of kinetic friction (μk = 0.20). The frictional force (Ff) is determined by multiplying the coefficient of friction by the normal force, which is equal to the weight of the box (mass x gravity). In this case, the frictional force is 5 N, indicating the force exerted on the floor. The discussion highlights confusion regarding the distinction between the force on the box and the force on the floor. Understanding these forces is crucial for solving related physics problems.

Homework Statement


you push a 25 kg box across a wooden floor at constant speed. how much force do you exert on the floor? (mu(k) = 0.20

Homework Equations



Ff=<uFn

The Attempt at a Solution


this is wat i get so far
mass = 25kg
uk= .20

.20<.20x25
.20<5

is this correct? I am confuse coz of how much force you exert on the floor not on the box?
i need help guys

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...
