A particle of mass m = 1.50 kg moves along one dimension and is subject to a single
force, whose potential energy function is given by U(x) = x4 – 2x2 + 4 (where U is
measured in Joules and x is measured in meters). At the moment when the particle is
located at position x =
1.50 m, its speed is v = 2.50 m/s.
