I am having a hard time to solve this using matlab. Please help me. Thank you very much.

11 Let us plot projectile trajectories using equations for ideal projectile motion: x(t) = Xo + (vo cos(80))t Where y() is the vertical distance and x() is the horizontal distance travelled by the projectile in metres, g is the acceleration due to Earth's gravity 9.8 m/s and t is time in seconds. Let us assume that the initial velocity of the projectile vo 50.75 m/s and the projectile's launching angle ,-5t/12 radians. The initial vertical and horizontal positions of the projectile are given by yo 0 m and xo- 0 m. Plot y vs t and x vs. t in two separate graphs with the vector t 0:0.1:10 representing time in seconds. Give appropriate titles to the graphs and label the axes. Make sure the grid lines are visible
