Please provide the matlab code and script file. Thank you!

Both 6.27 and 6.28, provide the matlab code and script file as well for both. Thank you!!

6.20 Real mechanical systems may involve the deflection linear springs. In Fig. P6.20, a block of mass m is released a distance h above a nonlinear spring. The resis- tance force F of the spring is given by F--(kid + k2d3/2) Conservation of energy can be used to show that 2k2d5/21 Solve for d, given the following parameter values: k1- 40,000 g/s, k-40 g/(s m), m- 95 g, g 9.81 m/s and h 0.43 m
