Question $12(2$ points$)$

LIsten

A block of mass $m$ is sliding down a slope inclined at $52$ to the horizontal. What is the acceleration of the block down the slope if the coefficient of friction acting between the surfaces is ${}_k=0\mathrm{.}38$

Newtons' Second Law: $F_{\text{n}\text{o}\text{t}}=ma$

Kinetic friction, $f_k={}_{k}N$

$11\mathrm{.}2\frac{m}{s^2}$

$0\mathrm{.}718\frac{m}{s^2}$

$3\mathrm{.}76\frac{m}{s^2}$

$5\mathrm{.}43\frac{m}{s^2}$
