1. Use graphical method f(mass)=0 to find the unknown mass of the following problem. Write function in MATLAB to plot the solutions. Please take help from book Example 5.1. a. Velocity v=36 m/s, C 0.25 kg/m, g=9.81 m/s-, t=4 sec. Hint: Rearrange the following equation. Use guess values of xi and Xu. gm gCd v(t) = tanh V ca b. Ift=10 sec, v=36 m/s, C0.25 kg/m, g=9.81 m/s?, can we still use graphical method to find the solution? Explain the solution problems in your own words. c. Can you test to find the root of the following functions. Use guess values of xy and Xu. i. x=e- ii. sin(10x) + cos(3x)=0 (V m
