Question #36407

A body of mass m= 1 kg is moving along the x-axis. Its potential energy is given by the function

U(x)=2(x^2−1)^2

a) What is the x -component of the force associated with the potential energy given by U(x) ? Give an expression in terms of x.

b) Suppose the body starts with zero speed at x=1.5 m. What is its speed (in m/s) at x=0 m and at x=−1 m?
