Question

A man weighing 600 N carries a load of 200 N on his head. If he climbs a height of 5 m. Find the work done.

Answer 1

Answer:

the work done is 300

Explanation:

because 600-200=400

and after doing 400N work he is very tired so he sit and the work done reduced

Answer 2

$\setlength{\unitlength}{1.6mm}\begin{picture}(30,20)\linethickness{5 mm}\multiput(0,0)(5,3.1){7}{\line(1,0){5}}\linethickness{3 mm}\put(35.5,17){\line(0,1){25}}\linethickness{0.2 mm}\put(-6.75,-4){\line(0,1){44}}\put(0,-1.5){\line(-1,0){7}}\linethickness{6 mm}\put(-7,-4){\line(1,0){43}}\put(-7,40){\line(1,0){43}}\put(34,28){\circle*{1.5}}\linethickness{2 mm}\put(2,2){\line(0,1){5}}\qbezier(-0.8,9)(-1,9)(1.5,7)\qbezier(-2.3,8)(-2.4,6)(-2.5,4)\qbezier(-2.5,4)(-2.8,2)(-3.2,0)\linethickness{4 mm}\put(-1.6,8){\line(0,1){2}}\put(-1.5,18.5){\circle*{4}}\linethickness{1.5 mm}\qbezier(-1.7,15)(-4.1,12)(-4.1,12)\put(-4.1,12){\line(0,-1){3}}\qbezier(0,15)(1.5,12)(1.5,12)\qbezier(1.5,12)(3,11.8)(4,11.6)\linethickness{0.2mm}\put(-2.95,10){\dashbox{0.1}(2.6,6)[l]}\end{picture}$

$\underline{\blacksquare\:\:\:\footnotesize{\red{\text{Figure:}}}}$

$\footnotesize{\text{Weight of the man = 600 N}}$

$\footnotesize{\text{Weight of the load = 200 N}}$

$\footnotesize{\therefore\:\:\text{Total weight = (600+200) N = 800 N}}$

$\footnotesize{\text{Now , Height he climbed up = 5 meters}}$

$\footnotesize{\therefore\:\:\text{Work done =}\: (weight \times height)}$

$\footnotesize{\implies\text{Work done =}\: (800 \times 5)\:Joules}$

$\footnotesize{\implies\boxed{\text{Work done =}\red{\:4,000\:Joules}}}$
