(a) At what position is the magnitude of the force on a mass in a mass–spring system minimum: (1) x = 0, (2) x = – A, or (3) x = + A? Why? (b) If m = 0.500 kg, k = 150 N/m, and A = 0.150 m, what are the magnitude of the ...A 0.25-kg object is suspended on a light spring of spring constant 49 N/m and the system is allowed to come to rest at its equilibrium position. The object is then pulled down 0.10 m from the equilibrium position and ...How much mass should be at the end of a spring (k = 100 N/m) in order to have a period of 2.0 s? The oscillations of two oscillating mass–spring systems are graphed in Fig. 13.25. The mass in System A is four times that in System B. (a) Compared with System B, System A has (1) more, (2) the same, or (3) less energy. ...Two masses oscillate on light springs.
