$E_{p} = W = 166, 48 J$ $E_p=W=166,48J$

Explanation:

$E_{p} : Potential energy of object$ $E_p:"Potential energy of object"$
$W : Work$ $W:"Work"$
$m : Mass of object$ $m:"Mass of object"$
$g : 9, 81 \frac{m}{s^{2}}$ $g:9,81 m/s^2$

$E_{p} = W = m \cdot g \cdot h$ $E_p=W=m*g*h$

$E_{p} = W = 8 \cdot 9, 81 \cdot 3 \cdot \frac{sin π}{4}$ $E_p=W=8*9,81*3*sin pi/4$

$E_{p} = W = 166, 48 J$ $E_p=W=166,48J$
