The force on an object, acting along the x axis, aries as shown in the figure. Determine the work done by the force to move the object (a) from x=10.0m, and (b) from x=0.0 to x=15.0m. Note: The answer suppose to be A) 2.8 X 10 3 J B) 2.1 x 10 3 J .....the line where the 13.5 is kind of threw me off.... I'm assuming its 13.5 rather than 14. Thanks

ravi pratap · Answer

a) W = (1/2)(3)(400) + (7 - 3)(400) + (1/2)(10 - 7)(400) = 2800 J b) W = W 0-10 + W 10-15 = 2800 + (1/2)(12 - 10)(-200) + (13.5 - 12)(-200) + (1/2)(15 - 13.5)(-200) = 2150 J I think it can help you .
