1.	A trolley filled with sand moves on a smooth horizontal surface with a velocity V_(0). A small hole is made at the base of it from which sand is leaking out vertically down at constant rate. As the sand leaks out(a) the velocity of the trolley remains constant (b) the velocity of the trolley increases(c ) the velocity of trolley decreases(d) the momentum of trolley + leaked out sand is conserved
