# Energy conservation on a non-smooth incline

APPHMC-NYSBG4

A block is initially held at rest on a non-smooth incline of angle $\theta = 30.0 deg$ relative to the horizontal.

If the block is released and it slides through a distance of $5.0 m$ on the incline, what would be its speed at the bottom of the incline? The coefficient of kinetic friction between the block and the incline is $\mu_{k} = 0.3$.

A

$4.854 m/s$

B

$7.004 m/s$

C

$8.381 m/s$

D

$9.905 m/s$

E
