Unformatted text preview: refresh you). 4. Problem 2.9. Use inv(a)*b or a\b to solve these simultaneous equations. Your results should be: x_values = 0.66260.13263.0137 2.83551.08520.8360 5. Problem 2.10  Use plotyy(x1,y1,x2,y2) to plot the height and velocity of the ball as a function of time. Use a time base of 10 seconds in 0.01 increments. Be sure to include proper labels and title in your plot and submit with your homework. To label the righthand (velocity) axis, use text(10.8,0,'Velocity in meters/sec','rotation',90) following ylabel for the lefthand (height) axis . As a test case, use an initial height above ground of 200 meters with an initial velocity of 20 meters/sec. The ball should reach ground level in (approx) 8.7 secs when read from your height vs time plot. Your input should be: Please enter initial height in meters: 200 Please enter initial velocity in m/s: 20 (Continued next page) EGR 115 Your plot should be: EGR 115...
