Hi everyone(adsbygoogle = window.adsbygoogle || []).push({});

I have a question

A force acting on an object moving along the x-axis is given by Fx=(10x-2.0x^2)N

Where x is in m. how much work is done by this force as the object moves from x=-1 to x=+6

My answer was:

when it says the object moves from -1 ro +6, that means it looks like triangle and the hight will be 6m

I used this formula to getthe area of triabgle

Wab = 1/2 (base) (high), where the high is 6, but what is the base?

Here I am lost
