Consider the spring system shown in Figure P7

A mass

is placed on top of a vertical spring and comes to rest after causing

a vertical deflection

Δx

Δx = 5.2 m

and the spring stiffness is

= 5.9 N/m, which of the following is the

correct value of the mass (M)

Assume the system is in equilibrium and the acceleration due to gravity is

g = 9.8 m/s².

Figure P7. Mass–spring system in static equilibrium

M = 8.64 kg

M = 31.31 kg

M = 6.26 kg

M = 3.13 kg
