Question

Please help with this exercise in Matlab

4 The range of an object shot at an angle θ (with respect toxaos), with the initial velocity of Va (in the absence of air resistance), is calculated by the following formula: va , sin(20) Range (0 052) And the trajectory of object is given by where h is the height of the object at each x location and g 9.81 m/s. Using n/8 increment size for the angle and Vo-10 m/s, plot the trajectories of the object in one figure with respect to x. (Hint: follow these steps: 1) For each value of θ find the range. 2) Create x as a vector starting from 0 to the computed range, 3) Compute h using θ and x from steps 1 and 2, 4) Plot h as a function of x. 5) Use hold on for the next plot (Use different colors for the plots and don't forget to put legends and labels). a) Create a vector for θ including 100 equally-spaced elements, and determine at which angles the maximum and minimum ranges occurs What is the maximum height of the object at the angle determined in part b. b) c)
