Question
Translation:
Suppose an horizontal force F(x) is acting over a box of 2kg on a horizontal surface. The force F varies in line according to the position of the box illustrated below. Find the Work done by the force F(x) when the box displaces from 0m to 20m
"FuerzaAplicada"= Applied Force
"Posicion"= Position
Explanation / Answer
work done=area of trainagle formed by graph
w=1/2XbaseXheight here base=displacement , height= force
base=20 m height=30-15=15N
w=1/2x20x15
w=10x15
w=150J
