The graph for this data represent the potential energy of a mass of 1.25 kg. The mass has a speed of 8.0 m/s at 3.0m. They system is frictionless

1. determine the total energy (in joules) of the mass when at 3.0m

2. what position does the object travel the fastest.

3.what range of position could the mass be

smallest position:

largest position:

Position (m).       Potential (j)
