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 = * m * v2. where m = mass and v = velocity. The green ball has potential energy due. to its height. The purple ball has kinetic. energy due to its velocity. 1  If you double the mass of an object, you double the kinetic energy.
