(4 points) The Hamiltonian has the same dimension as A. the product of someones mass and height B. the product of someones weight ( mg ) and height ( h ) C. work D. action 2. (3 points) If a systems Hamiltonian is H ( q 1 ,q 2 ,p 1 ,p 2 ,t ) = p 2 1 2 m 1 + p 2 2 2 m 2 + k 2 ( q 1- q 2 ) 2 , where m 1 , m 2 , and k are positive constants, and m 1 6 = m 2 , which of the following quantities are conserved? A. q 2 B. p 1 + p 2 C. H 3. (2 points) For the Hamiltonian system H ( q,p,t ) = c p 2- c 1 q 2 + c 2 q 4 , where c , c 1 , and c 2 are positive constants, exactly how many points on the phase plane are stationary (namely satisfy q = 0 and p = 0 simultaneously)? A. 1 B. 2 C. 3 D. 4 4. (2 points) An object is described by the Hamiltonian H = p 2 2 m + V ( q ) where V ( q ) = mgq at q > 0 and V ( q ) =- Kq at q < 0. Assume that m , g , and K are positive constants, and K mg (think of a ping-pong ball that bounces perpetually on the ground).on the ground)....
