I want help with question 2

 

1. Consider a Hamiltonian function of the form
p2
H(p, x)
+ V(τ).
2m
Here p and x are one-dimensional.
(a) Write down Hamilton's equations.
Physically interpret p, m, V for this particular system.
(b) Using Hamilton's equations, solve for p as a function of m and i.
(c) Rewrite the quantity
p2
T=
2m
as a function of m and i, and hence provide a physical interpre-
tation for this quantity.
2. Repeat the above question with a Hamiltonian of the form
H(p, T) =
+ V(7),
2m
where p(t) and 7(t) are now vector functions in 3-dimensional space.
(Given what you have already done, this should be very easy.)
Hints:
p = (Pa, Py, Pz);
Ë = (x, y, z);
7² = p·p = p + p, + p?.
