A particle is moved along the x-axis by a force that measures 10/(5 x)2 pounds at a point x feet from the origin. Find the work W done in moving the particle from the origin to a distance of 5 ft. W

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

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?

Does current flow through or across a resistor?
