Answer to Question #3219 in Mechanics | Relativity for ZherVin

Question #3219
Three springs of force constants, K1=10N/m, K2=12.5N/m, and K3=15N/m are connected together and attached to a mass of 0.50kg. The mass is then pulled to the right and released. Determine the period of the motion when the springs are combined in series and parallel.

When the springs are combined in series
1/K=1/K1 +1/K2 +1/K3
thus
K=(K1 K2 K3)/(K1 K2 + K2 K3 + K1 K3 ).
When the springs are combined parallel
