In this task, you will design a scale model of the solar system. A simple scale model would depict the Sun and eight planets to scale. Research online for resources that provide information on creating a model that scales up to the proper dimensions of the solar system. Use this site to calculate a scale for the various bodies in the solar system by specifying a fixed size for the Sun. (Note: distances between planets in the solar system are extremely large, so it is recommended to perform this task in an open park for best results.) Record your findings and provide a detailed explaination of how you visualized your scale model. Link to the image is exploratorium. edu/ronh/solar_system/

Fft review: linspace, fs, fftshift, nfft 1. generate one second of a cosine of w,-10hz sampled at f, = 100hz and assign it to x. define a tt as your time axis 2. take 64 points fft. 3. as you remember, the dft (which the fft implements) computes n samples of s2t where k-0,1,2, n -1. plot the magnitude of this 64-points fft at range 0 to 63, what do you think of this graph? 4â·to get the x-axis into a hz-frequency form, plot this 64-points fft between-50 to 50 (the 100hz sampling rate) and have n-points between them. 5. according to your figure, what frequency is this cosine wave at? 6. remember that the fft is evaluating from 0 to 2ď€. we are used to viewing graphs from-ď€ to ď€. therefore, you need to shift your graph. 7. now according to your shifted graph. what frequency is this at? 8. note that the spikes have long drop-offs? try a 1024-point dft. note that the peak is closer to 10 and the drop-off is quicker. although, now sidelobes are an issue

There are two routes similar in terrain; however, one route has an incline of approximately 28 degrees, and you must decide on which route to take. what is the maximum road grade that your fully loaded ecv can climb?

What is friction? how does it affect the motion of an object?
