This question needs to be answered and works in MATLAB

A 70 lb bag of rice is being pulled by a person by applying force F at an angle as shown. The force required to drag the bag is given by: 70 where = 0.35 is the friction coefficient. (a) Determine F() for = 5, 100, 15, 20, 25, 30, 35. (b) Determine the angle where Fis minimum. Do it by creating a vector with elements ranging from 5 to 35 and spacing of 0.01. Calculate F for each value of and then find the maximum Fand associated with MATLAB's built-in function max
