AI Thread Summary
To calculate the force required to push an 870kg block up an 80m ramp at a constant speed, the coefficient of sliding friction is 0.32 and the ramp's angle is 16 degrees. The initial attempt to calculate the force incorrectly combines units, as the coefficient of friction is unitless and cannot be added to forces measured in kg*m/s^2. It is essential to rearrange the variables to ensure consistent units throughout the equation. Applying Newton's second law for a system in equilibrium (where the sum of forces equals zero) is crucial for solving the problem accurately. Proper unit management and understanding of the physics involved are key to finding the correct force.

HELP! FORCE with RAMP!

Homework Statement



What force is required to push a 870kg block up an 80m ramp at a constant speed. The block has a coefficient of sliding friction of .32 with the ramp, and angle of 16 degrees from the ground.

Homework Equations





The Attempt at a Solution


F=(.32)+((870)(9.81)(sin(16))?

Well, first you should realize that your units don't match up. You can only add similar units, and they should be the same as the units on the other side of the equal sign. Try rearranging your variables to give units of kg*m/s^2. Currently, you are attempting to add a unit-less coefficient to something with units of kg*m/s^2.
 


If you get stuck again, let me know, and don't forget to use Newton's second law for a system in equilibrium (sigma)F = 0
 

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...
