Depicts the potential energy of a 400-kg pallet that slides from rest down a frictionless roller conveyer ramp, then moves across a frictionless horizontal conveyer, and finally encounters a horizontal spring at x=4.0m. When the pallet encounters the spring, it momentarily comes to rest at x=6.0m. A) What is the force constant of the spring?
B) At what height h above the horizontal conveyer did the pallet begin sliding from rest?
C) What is the angle of inclination of the conveyer ramp?
D) What will be the speed of the pallet at x=6.0m if it begins sliding from rest at x=0?
Please provide explanations along with answers. I do not understand where to begin. Thank you so much.

An insulated 40 ft^3 rigid tank contains air at 50 psia and 120°f. a valve connected to the tank is now opened, and air is allowed to escape until the pressure inside drops to 25 psia. the air temperature during this process is kept constant by an electric resistance heater placed in the tank. determine the electrical work done during this process.
