5.0\,\text{kg}

block is released from rest at the top of a

3.0\,\text{m}

-long incline that makes an angle of

30^{\circ}

with the horizontal. The coefficient of kinetic friction on the incline is

0.20

. At the bottom of the incline, the block immediately slides onto a horizontal rough surface (

\mu_k = 0.10

) and travels an additional

2.0\,\text{m}

along that surface. Calculate the block’s speed after it has traversed the entire

5.0\,\text{m}

path.
