Exercise 85

(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 force on the mass and the acceleration of the mass at x = 0,0.050 m, and 0.150 m
