option B

Explanation:

given,

mass of the box = 1 Kg

spring constant = k = 1000 N/m

spring is compressed upto = 15 cm = 0.15 m

coefficient of friction = μk =0.4

using conservation of energy

$\dfrac{1}{2}kx^2 = \dfrac{1}{2}mv^2$

kx^2 =mv^2

$v = \sqrt{\dfra{k}{m}}x$

$v = \sqrt{\dfra{1000}{1}}\times 0.15$

v = 4.74 m/s

so, the velocity of the box = v = 4.74 m/s

hence, the correct answer is option B
