A conservative force F⃗ is in the +x-direction and has magnitude F(x)=α/(x+x0)2, where α=0.800N. m2 and x0=0.200m. (a) What is the potential energy function U(x) for this force? Let U(x)→0 as x→ω (b) An object with mass m = 0.500 kg is released from rest at x = 0 and moves in the +x-direction. If F⃗ is the only force acting on the object, what is the object’s speed when it reaches x = 0.400 m?

U=α/(x+x_0)^2

v=1.88m/s

Explanation:

We have that

(a)

The potential is calculated by using

(b)

m=0.5kg

The acceleration can be obtained if we calculate the force for x=4, and after we compute the acceleration

and finally, we can use the equation for the final speed

I hope this is useful for you
