Case 1: Car is at rest and engine delivers torque for one second. Case 2: Car is moving at a constant velocity on the flat mass and the engine delivers a torque using the same amount of energy as in case 1.

Since the work done on a body is equal to the force times distance covered when the force is being applied. So in this case more work will have to done to apply the same force for the same duration. Meaning more energy is required to achieve the same amount of acceleartion. But let's look at...

A car of mass 1kg rests on top of a large flat mass of 1,000,000 kg (10^6 kg). They are at rest (relative to the sun) in space. The car has a battery and an electric motor with 100% efficiency. We can assume that when a torque is applied to the wheels, they roll on the surface of the flat mass...

BTW, I found this (nonequispaced fast Fourier transform or nonuniform fast Fourier transform): http://www-user.tu-chemnitz.de/~potts/nfft/

Yes, its exactly the same thing.

Yes, I don't need all 6000 coefficients. Unfortunately, I have to get the Fourier coefficients because my boss told me to:( Otherwise I would also use other interpolation techniques.

Thanks for the reply. Perhaps I was not clear about a few aspects. I need Y as a continuous function of X where the the function consists of only sines and-or cosines. So basically I need the Fourier coefficients. I need this in order to be able to approximate high derivatives of the the...

Dear people, I am trying to analyze data from test bench which consists of a magnetically levitated spindle. We have a rotor/spindle which rotates and moves vertically up and down as it rotates. I measure the angle of rotation and the vertical displacement at a steady rate of 10,000 samples...
