(14-25) A mass m is connected to two springs, with spring constants k1 and k2, in two different ways

(14-25) A mass m is connected to two springs, with spring constants k1 and k2, in two different ways as shown in Fig. 14-32a and b. Show that the period for the configuration shown in part (a) is given by T=1/2π√m(1/k_1+1/k_2)and for that in part (b) is given by T=1/2π√m/k_1+k_2, Ignore friction.
