Explanation / Answer

Here,

spring constant , k = 2.6 N/m

mass of block , m = 430 gm

m = 0.430 Kg

time period of oscillations , T = 2pi * sqrt(m/k)

Now , for time difference for phase difference = pi/2

time difference = time period * (pi/2)/(2pi)

time difference = 2pi * sqrt(0.430/2.6) * (1/4)

time difference = 0.639 s

the time difference for two oscillations differe in phasse by pi/2 is 0.639 s
