An object is moving in one dimension (along the x-axis). The potential energy of the system is shown as a function of horizontal position in Figure 2, the graph above. There are no other forces on this object aside from the conservative force associated with this potential energy function. If the object is released from rest at the point x = 10.5 m, what is the kinetic energy (in joules) of the object when it reaches the point x = 6.0 m? Round off your answer to the nearest joule. Question 4 1 pts Again referring to the graph of potential energy as a function of position shown in figure 2, if the object is released from the point x = 4.0 m (in this case it is not at rest when it is released), what is the minimum amount of kinetic energy (in joules) it must have at that point in order to reach the point x = 10.5 m? Again, round off your answer to the nearest whole joule. Figure 2: -5 -10 -15 2 4 6 10 Distance in meters Potential energy in joules
