An object of mass m=2kg is part of a system and it is subject only to conservative forces and constrained to move along a horizontal line such that the potential energy of the system is given by the function U(x)=(−10)/(x2+1), where x is in meters and U is in joules. The graph of the function is shown in the image. The object is released from rest at position x=−5m, moves in the positive direction, and later passes position x=−1mx=−1m. (b) Explain how the object’s speed changes as the object travels from x=−5m to x=−1m. Justify your answer.
