Calculating Frictional Force on Inclined Block | 43 kg Mass | 19° Inclination

AI Thread Summary
To calculate the frictional force on a 43 kg block resting on a 19° incline, the coefficients of static and kinetic friction are given as 0.42 and 0.36, respectively. The gravitational acceleration is 9.8 m/s². Since the block is at rest, the static friction is the relevant force to consider. By applying Newton's first law, one can identify the forces acting on the block, including gravitational and frictional forces, to determine the frictional force in Newtons. The solution involves calculating the normal force and then using the static friction coefficient to find the frictional force.

a block is at rest on the incline shown in the figure. the coefficients of static and kinetic friction are s = 0.42 and k = 0.36 respectively. The acceleration of gravity is 9.8 m/s^2. the angle of inclination is 19 degrees.

what is the frictional force acting on the 43 kg mass? answer in units of N.


Honestly I have no idea what to do on this problem...

If the block is at rest, you need only to identify all the forces acting on the block and apply Newton 1 to solve for the unknown friction force.
 

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...
