hi im trying to right to solve this to get the laplase transform

this is my code but it's not right

syms s t m1(t) m2(t) l1(t) l2(t) g(t) a1(t) a2(t) A1(s) A2(s)

da1=diff(a1,t)

d2a1=diff(da1,1)

da2=diff(a2,t)

d2a2=diff(da2,t)

M1=(m1+m2)*(l1^2)*d2a1+m2*l1*l2*d2a2+(m1+m2)*g*l1*a1==0

M2=m2*l1*l2*d2a1+m2*(l2^2)*d2a2+m2*g*l2*a2==0

conda1= a1(0) == 0.5;

conda2= a2(0) == 0;

conda11= diff(a1(0)) == 0.8;

conda12= diff(a2(0)) == 0;

lM1=laplace(M1)

lM2=laplace(M2)
