Question

A conservative force F(y) acts on a 0.400 kilogram object that moves along the y-axis. This is the only force on the object [do not assume that this force is the gravity force]. The potential energy U(y) associated with the conservative force F(y) is graphed below as a function of height y. Note that between the points A and B the potential energy U(y) is a straight line, and between the points C and D the potential energy U(y) is also a straight line. Assume that when the object is at the position y=5.00 meters, the Mechanical Energy of the particle is 4.00 Joules. What is the vector force F(y) on the object at the position y=1.50 m? Draw the graph of the mechanical energy E_each vs. y on the above plot. Be sure to label it. Draw the graph of the check energy k vs y on the above plot. Be sure to label it. What is the object's speed at y=2.00 m? What are the positions of the object's turning points? If the object is travelling down when it is at position y=1.50 m, then is the object speeding up or slowing down?

Can you help me solve for d and f!!
