2. A vehicle with a total mass of 1 000 kg drives up an incline of 0º at a constant speed while in third gear. The third gear ratio is 1.5:1 and the rear axle ratio is 4:1. While on the incline the engine rotates at 3 600 rev/min and develops a brake power of 65 kW. The losses in the drive train amount to 15%, the diameter of the drive wheels is 640 mm and the air and other resistances at this speed amount to 210 N. a) Calculate the inclination of the slope. (15º) b) If fourth gear with a ratio of 1:1 is engaged, the vehicle loses speed. Calculate the deceleration if the four wheels each have a mass of 12 kg and a radius of gyration of 300 mm. Assume that the brake power of the engine at the lower speed decreases by 3 kW. (0.96 $m/s^2$)

• Must throw an exception. I should not be able to type in any a character or character key. It should prompt me to enter a number from 1-9. • Input Validation: It should not let me enter in any number. It should ask you to enter a number from 1-9 • Your code should allow you to play again. You will need a loop. • You should add a feature like a counter to track wins and lost. Turtle another feature showing you result. • Add a new option. Allow me to choose option 1 prompt the user or option 2 setting the list. This required. Use an if elif. • Please make sure you include instruction in your program. • Detail Algorithm should include all for, if statements in the process, all function explanations. The input should consist of all explanation of input. Output should consist all the outputs in your program. • Every line should consist of a comment use key words like Get, Ask, Prompt the user, and Calculate or Compute, and Display. Possible Points Off • No algorithm -40 points • No comments -30 points • Some algorithm will get you -20 points off • Some comments will get you -15 points off

Consider a one-dimensional chain of spins $\vec{S}_n$ coupled via ferromagnetic nearest-neighbor exchange $J$. The distance between nearest-neighbors is $a$. A uniform magnetic field $\vec{B}_0 = B_0 \hat{z} = h\omega_0 \hat{z}$ along the $z$ direction is applied to the system. The equation of motion for arbitrary spin is $\frac{d\vec{S}_n}{dt} = \frac{J}{\hbar} \vec{S}_n \times \left( \vec{S}_{n-1} + \vec{S}_{n+1} + \frac{1}{J}\vec{B}_0 \right)$ Derive the equations of motions for the x, y and z components of an arbitrary spin $\vec{S}_n$. To do that, just write down the above equation of motion for the three components of spin $\vec{S}_n$. Assume that in absence of oscillations/fluctuations, the spins are perfectly aligned along the z direction with $\vec{S}_n = S\hat{z}$. Determine the (three) coupled equations for each of the component of $\vec{S}_n$; that is $\frac{dS^u_n}{dt}$ where $u=x, y$ and $z$.
