Below is the potential energy diagram for a 50 gram particle. If the particle'smechanical energy is 7J:10U (1)9876543210 1 2 346 7 8 9 1011 12x (cm)A. Draw a line corresponding to the total Energy on the diagram.B. Assume the particle is moving in the positive x direction. Where is the particlespeeding up?C. Assume the particle is moving in the positive x direction. Where is the particlelowing down?D. Where are any turning points in the particle's motion?E. What is the particle's speed at x=5 cm?F. What is the particle's maximum kinetic energy? Where does that occur?G. Suppose the particle's energy is decreased to 4J while the particle is betweenpositions x = 7 cm and x = 9 cm. What is the particle's new maximum speed?Where does that occur?

According to our policy, I am doing first three subparts and rest you can upload separately.
