1.A tall pole and a short pole (both having the same diameter and mass density) are both standing straight up. Both are allowed to tip and fall, starting from rest, at the same time. Which reaches the ground first?

Question

2.When a non-vertical projectile strikes the ground, which part of the momentum of the projectile is conserved during the collision?

Answer 1

The torque on each is massdensity*h*gh/2 or
T=massdensity*g*h^2/2
of course, h is different.

angular acceleration is Torque/momentinertial
where momentinertia=massdensity*h*h^3/3

angular acceleartion= k/h^2

so, the longer the heigth, the slower the falling.
check my thinking.
