A block of mass $5 \, \text{kg}$ is placed at rest on a rough surface. If a force of $30 \, \text{N}$ is applied parallel to the surface and the block slides through a distance of $50 \, \text{m}$ in $10 \, \text{s}$ , then the coefficient of kinetic friction is (given, $g = 10 \, \text{m s}^{-2}$ ):

A
$0.60$
B
$0.75$
C
$0.50$
D
$0.25$
