Physics 325 Spring 2011 Discussion 1 January 24, 2011 Problem 1 A particle of mass m is constrained to move in a straight line, inside a force field with potential energy kx 2 , where x is the position measured from origin, and k is a positive constant. If the particle starts at rest from x = 2 a , what is the particle’s speed when it reaches

Unformatted text preview: x = a ? Hint: Use conservation of energy. Problem 2 Two objects are interacting through an attractive force of constant magnitude F . Assume that there is no other force acting on the objects. (a) Is the momentum of object 1 conserved? (b) Is the combined momentum of both objects conserved?...
