A mass 􀝉􀬵 􀵌 1 􀝇􀝃 is attached to a spring with a spring constant 􀝇􀬵 􀵌 5 􀯇

􀯠, which is
attached to a solid mounting. A second mass 􀝉􀬶 􀵌 1 􀝇􀝃 is attached to a spring with
spring constant 􀝇􀬶 􀵌 6 􀯇
􀯠, which is attached to the bottom of 􀝉􀬵. Initially, 􀝉􀬵 is at rest
and in equilibrium, while 􀝉􀬶 is at rest 1 􀝉 below its equilibrium position.
