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.
KE = 0.5 â¢ m â¢ v2 where m = mass of object v = speed of object This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four.
