4. (a) An object thrown vertically Write and test a function that computes the time requ where h-100 m, vo-50 m/s and 8-9,8 ally with a speed vo reaches a height h at time t, where: 10 vo re ired to reach a specified height h, for a function's input should be h, vo, and g. Test your function for the case vo-50 m/s and g-9,81 m/s? by writing a MATLAB code which calls the function. 110) (b) Given: A- 76 5 -4 1-3 2 10 using array rieht division, (i) A divided by B using array left division (iv) and A times B using () Find the results of A times B using the array product, (i) A divided by B Matrix multiplication
