Answer:
given function is
formula for newton's method is
so derivative of function is
now put values and solve
or you can also use MATLAB code to solve
i.e
function p= newton(x)
e=0.001;
for i=1:100
if abs(d(x))>e
if abs(k(x))>0
xm=x-(k(x)/d(x));
x=xm;
else
end
break;
end
end
disp(x)
disp(k(x))
return;
Answer:
C. The initial momentum should be equal to the final momentum due to the conservation of momentum.
Since m/(M+m) < 1, v_1 > v_0.
Explanation:
Wrong -> A. Since the smaller particle still moves after the collision, it has a kinetic energy.
Wrong -> B. The total initial momentum is equal to the momentum of the smaller particle. Therefore, the momentum of the objects that stuck together is equal to that of the smaller object.
Wrong -> D. Since the bigger object is initially at rest and the surface is frictionless, the direction of motion will be the same as the direction of the smaller particle.
