PHY 241 Homework Assignment Learning Unit 5 A 2.00 kg object is moving without friction along the x-axis. The potential energy curve as a function of position is shown in the figure, and the system is conservative. The speed of the object at x = 2.0 m is 3.0 m/s. (a) 1%at is the work done by the force between x = 0.0 m and x 2.0 m? (b) 1%at is the object's speed at 3.0 m along the *x-axis? (c) Are there any turning points between x = 1.0m and x = 7.0 m? If yes, what is the position of the turning point(s) of the object?
