4\,\text{kg}

block slides up a rough incline that makes an angle of

30^{\circ}

with the horizontal. Its initial speed at the bottom is

, and the coefficient of kinetic friction between the block and the plane is

0.30

. How far (along the incline) will the block move before coming to rest? (a)

3.6\,\text{m}

(b)

2.0\,\text{m}

(c)

2.4\,\text{m}

(d)

4.8\,\text{m}
