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

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
