A proton moves along the x-axis where some arrangement of charges has produced the potential V(x)=Vosin(2πx/λ),where Vo = 3800 V and λ = 1.0 mm. a) What minimum speed must the proton have at x = 0 to move down the axis without being reflected? b) What is the maximum speed reached by a proton that at x = 0 has the speed you calculated in part A?

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the

This energy transformation diagram represents the energy of a skateboarder moving along a half-pipe. as she skates toward the top of the half-pipe, her original kinetic energy is converted to potential energy and friction. how much of the energy is potential?
