A spring mass system (spring constant K and mass m ) lies on a smooth horizontal surface with one end of spring being rigidly fixed. At
t=0the mass is pulled with a constant horizontal force F. Speed of the mass after time
tis (a)
(Ft)/(m)(b)
(F)/(\sqrt(Km))sin(\sqrt((K)/(m))t)(c)
(2F)/(\sqrt(Km))sin(\sqrt((K)/(m))t)(d)
(F)/(\sqrt(Km))cos(\sqrt((K)/(m))t)
