2. An object of mass m=5.0 kg 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. i. Explain how the object's speed and acceleration (magnitude only) change as the object travels from x =-5 to x = +5. Justify your answer. (2 marks) ii. At position x: 0 m, the object is given an initial velocity of 1 m/s in the negative direction. What is the farthest position to the left and farthest position to the right that the object can reach? Justify your
