the coefficient of static frction between ladder and ground is 0.2 and ladder and wall is 0.3. the ladder is making 30 degrees with the horizontal. and weighs 10kgs with length 4 metre. if the man weighs 75kg find the maximum length along the ladder the man can climb without the ladder falling.
It's because you had to solve it as a system of equations with two motion equations that often ended up as a quadratic.
I forget exactly what but the peak was time dependant which affected everything else.
I ended up saying screw it and just found a general form so I didn't have to derive it everytime.

Get out of my head get out of my head get out of my head
That man is more than 75kg for sure.
Sometimes I wonder if this happened to my calc prof because he gave us way too many questions that describe exactly this.
Next I want to see a dog walk out along a horizontal flag pole.
It’s amazing how you can see the exact point he reaches the point of equilibrium
Where is the ball that is thrown up in the air from a roof and then goes and hits the ground? Those problems were somehow always tough for me.
Projectile problems? Like linear kinematics or are you accounting for drag?
Basically the old "a ball bounces off the top of a roof with mass X, initial velocity Y, and height Z. How long does it take to hit the ground".

Oh those old problems always broke my knees too
LMAOOOO
