Question regarding projecticle in freefall disregarding air resistance
This equation: $y(t)= y_0 + v_0 t -1/2gt^2$ describes the complete vertical motion from the moment the stone is thrown of the tower $t=0$ to the moment the stone hits the ground. So solving: $y_0 + v_ …

How to find the wavefunction that solves an infinite square well with a delta function well ...
If the delta potential is strong enough, there is also a solution possible for $E<0$. Define $\kappa^2 = 2m |E|/\hbar^2$ with $\kappa > 0$.
Then for $0<x<L/2$ we have $$\psi(x)=C\sinh(\kappa x)$$
and …
