This video shows the steps to design a differential equation 2nd order in Simulink using basic blocks in Matlab 2017b.
Differential Equation in Simulink
2 x” + 2 x’ + 3 đŠ’ + đ„ + 2đŠ = 0,
đŠ” + đ„’ + 2 đŠ’ + 2đŠ = sin(đđĄ)
Initial Conditions
đŠ'( 0 )= â1
y( 0 )= 1
x” = -1/2 ( 2 x’ + 3 đŠ’ + đ„ + 2đŠ)
đŠ” = sin(đđĄ) – đ„’ – 2 đŠ’ – 2đŠ

The maximum height âhâ achieved by an object thrown with a speed âvâ at an angle âthetaâ is given by h=v(sqr)*sin(theta)(sqr)/2g . Create a table showing the maximum height for the following values of v and theta. v=10 20, in steps of 2 and in steps of 10. Use suitable interpolation function to find âhâ corresponds to v=13 & 15 and theta = 55 to 65
