tazón = a·F·x^{2}+b·F·y^{2}

m·d_{tt}^{2}[z(t)] = a·F·x^{2}+b·F·y^{2}

(m/2)·d_{t}[z(t)]^{2} = a·F·(1/3)·x^{3}+b·F·(1/3)·y^{3}

(k+(-1))·2 = 3k

x(t) = ( ( (1/2)·(1/m)·( a·F·(1/3)+b·F·(1/3) ) )^{(1/2)}·t )^{(-2)}

y(t) = ( ( (1/2)·(1/m)·( a·F·(1/3)+b·F·(1/3) ) )^{(1/2)}·t )^{(-2)}

z(t) = ( ( (1/2)·(1/m)·( a·F·(1/3)+b·F·(1/3) ) )^{(1/2)}·t )^{(-2)}
