All sellers making retail sales of taxable goods or services in Nebraska are required to register with the state and collect and remit sales tax. As Nebraska is a Streamlined Sales Tax state, out-of-state businesses without a sales tax obligation are encouraged to register for sales tax purposes.
Since the kinetic energy increases with the square of the speed, an object doubling its speed has four times as much kinetic energy. For example, a car traveling twice as fast as another requires four times as much distance to stop, assuming a constant braking force.
When the skier is halfway up the hill the kinetic and potential energies are equal. A few hours later when the skier has reached the top of the mountain, their potential energy is at its maximum and their kinetic energy is zero. Kinetic energy is one half times the mass times the velocity squared. Kinetic energy = 1/2mv 2. Potential energy is the mass times gravity times the height.
