# Question: a At what position is the speed of a mass

(a) At what position is the speed of a mass in a mass–spring system maximum: (1) x = 0, (2) x = – A, or (3) x = + A? Why?

(b) If m = 0.250 kg, k = 1000 N/m, and A = 0.10m for such a system, what is the mass’s maximum speed?

(b) If m = 0.250 kg, k = 1000 N/m, and A = 0.10m for such a system, what is the mass’s maximum speed?
