possibly FriCAS can, it seems:
(2) -> DEiii := %pi * (39/100*y t+ 1/2)^2* D(y t,t) + a * sqrt(2*g*y t)
2 , +-------+
(1521%pi y(t) + 3900%pi y(t) + 2500%pi)y (t) + 10000a\|2g y(t)
(2) ----------------------------------------------------------------
10000
Type: Expression(Integer)
(3) -> solve(DEiii, y, t)
+-------+ 3 2
50000a t\|2g y(t) + 3042%pi y(t) + 13000%pi y(t) + 25000%pi y(t)
(3) -------------------------------------------------------------------
+----+
5\|y(t)
Type: Union(Expression(Integer),...)
But WARNING: I did not check the solution and I did not read the manual
:-)
