A block of mass \( 5 \mathrm{~kg} \) is on a rough horizontal surface and is at rest. Now a force of \( 24 \mathrm{~N} \) is imparted to it
\( \mathrm{P} \)
with negligible impulse. If the coefficient of kinetic friction is 0.4 and \( g=9.8 \mathrm{~m} / \mathrm{s}^{2} \), then the acceleration of the block is
(1) \( 0.26 \mathrm{~m} / \mathrm{s}^{2} \)
(2) \( 0.39 \mathrm{~m} / \mathrm{s}^{2} \)
(3) \( 0.69 \mathrm{~m} / \mathrm{s}^{2} \)
(4) \( 0.88 \mathrm{~m} / \mathrm{s}^{2} \)
