A certain mass stretches one spring foot and another spring foot. The two springs are then attached in parallel to a common rigid support in the manner shown in the figure below. rigid support m The first mass is set aside, and a mass weighing 4 pounds is attached to the double-spring arrangement, and the system is set in motion. If the period of motion is x/10 second, determine how much he first mass weighs. (Use g = 32 ft/s2 for the acceleration due to gravity.) Ib
