Question

Answer part (a) on a blank page. Matlab simulations must be written in script files with your names embedded. Attach your Matlab simulations (both .m and fig files) at the back. (a) For the simplified rocket model shown in Figure 2 Find the expression for the signal x (t) in terms of singularity ramp r(t) and unit step u (t) functions. Explain briefly how the expression is obtained, with graphical aids if possible. (4 points) From the expression you obtained in (a), reconstruct Figure 1 using Matlab. (6 points) (b) ----.+ 3 + + .3 252 -1.5 -1 -0.5 ī Figure 2: rocket sitting on the ground
