2.5\,\text{kg}

block is released from rest at the top of a

2.0\,\text{m}

long rough incline that makes an angle of

30^{\circ}

with the horizontal. It reaches the bottom in

1.5\,\text{s}

with uniform acceleration. Calculate the coefficient of kinetic friction between the block and the incline.
