An object of mass 4.0kg is moving along the x-axis. A
conservative force is exerted on the object. The potential energy U
associated with this force is given as a function of position x by
the equation U(x) = β 2x + 10x2 β 5x + 4 . This function
is shown in the graph provided. The kinetic energy of the object
when x = 0 is 20 J.
