Question

if 100 N force has 30 degree angle pulling on 15 kg block for 5 m. What's the work

Answer 1

$\underline{\underline{\Large{\bf{Given:-}}}}$

$\star\sf Force=F=100N$

$\star\sf Displacement=5m=S$

$\star\sf Angle\:obtained=30°$

$\underline{\underline{\Large{\bf{To\:Find:-}}}}$

$\star\sf Work\:Done=W$

$\underline{\underline{\Large{\bf{Solution:-}}}}$

$\sf We\:know\:that$

$\boxed{\sf W=FScos30}$

$\\ \sf\longmapsto W=100\times 5\times \dfrac{\sqrt{3}}{2}$

$\\ \sf\longmapsto W=500\times \dfrac{\sqrt{3}}{2}$

$\\ \sf\longmapsto W=250\sqrt{3}$

$\\ \sf\longmapsto W=250\times 1.732$

$\\ \sf\longmapsto W=433J$

$\underline{\therefore{\sf Amount\:of\:Work\:done\:is\:433J}}$
