5\,\text{kg}

block is projected up a rough plane inclined at

30^{\circ}

to the horizontal with an initial speed of

3\,\text{m/s}

. The coefficient of kinetic friction between the block and the plane is

0.30

. Take

g = 10\,\text{m/s}^2

. How far up the plane will the block move before coming momentarily to rest? (a)

0.90\,\text{m}

(b)

0.60\,\text{m}

(c)

0.30\,\text{m}

(d)

0.56\,\text{m}
