I need urgently a MATLAB code for the following problem

\#4 A shell moving with a velocity of known components vx2,vy2, and vz explodes into three fragments of masses m1,m2, and m3 at point A0 at a distance d from a vertical wall. Derive expressions for the speeds of the three fragment immediately after the explosion, knowing the coordinates xi, and yi of the points Ai (i=1,2,3) where the fragments hit the wall. With the following numerical values compute the 3 velocities: A1(5m,0);A2(12m;6m);A3(0 m;9m);d=12m;m1=5kg;m2=4kg;m3=3kg;v=40m/s;vy=30m/s;vz=1200
