Question 1: Referring to the system of the attached figure (Block A and B), how much energy is required to move block 'A' a distance 'd'?
Possible answers:
(1) None, since there is no friction.
(2) m1d
(3) m1^2d
(4) m1d^2
(5) gm1m2d / (m1 + m2)
Question 2: If block 'A' in the attached figure moves a distance 'd' starting from rest, find the kinetic energy stored in the block.
Possible answers:
(1) Cannot be determined without more information.
(2) m1d
(3) m1^2d
(4) m1d^2
(5) gm1m2d / (m1 + m2)
