2:53 how do you know that maximum friction means minimum pushing force? Can you please explain, because I don't understand what led to this conclusion. Thank you!!
please solve this problem, a 0.5 kg block is pushed 3 m at a constant velocity up a vertical wall by a constant force applied at an angle of 37 degree with the horizontal as shown at right . if the coefficient of kinetic friction between the block and the wall is 0.3. what is the work done by the force on the block.
sir force of friction is always opposite to direction of motion , as u said force is pushing a kind of upward so why not friction force is acting downward????????????
The question asks for the minimum force and when you are applying the minimum force, the block wants to move downward, which means to oppose the motion the friction will be up
Thank you, these types of problems were giving me a lot of trouble.

Oddly enjoyable to watch! Good stuff!
Thank you so much!
Thank you so much
Fun problem!

is F sub f the force of static friction?
Yh...it's the coefficient of static friction
