4. (a) The height and speed of a projectile launched with a speed of v, at an angle p is given by: h(t) = vet sing - g t; v(t) = (v - vigtsing + 2g2) The projectile will strike the ground when h(t)=0 which gives the time to hit thit = 2(v/g)sin p. Assume cp = 30, v = 40,9 = 9.81 m/s2; Using MATLAB relational and logical operators, write a program to find times when (i) the height is no less than 16 m and speed is simultaneously not greater than 36 m/s and (ii) the height is less than 10 m or speed is not less [12] than 35 m.
