A truck pulls boxes up an incline plane. The truck can exert a maximum force of $2,500 N$ . If the plane's incline is $(7 pi )/8$ and the coefficient of friction is $5/3$ , what is the maximum mass that can be pulled up at one time?

$m<=132,56" " kg$

enter image source here

$2500>=m*g*sin alpha+k*m*g*cos alpha$

$2500 >=m(g*sin alpha+k*g*cos alpha)$

$m<=2500/(g*sin alpha+k*g*cos alpha)$

$k=5/3" "g=9,81 m/s^2" "alpha=22,5 ^o$

$m<=2500/((3,75+15,11))$

$m<=2500/(18,86)$

$m<=132,56" " kg$
