(6 Marks) QUESTION 2 r(1) $10 ft Vo 300 ft 13 ft Figure 1 Consider the path of the projectile with initial velocity vector V, and initial height / launched at an angle o with the ground. The vector function r() describing the projectile is given as follows. Neglecting air resistance, the path of a projectile at time / launched from an initial height h with initial speed v, and angle of elevation o is described by the vector function r(1)= (v.cosahit h+(v. cosa) - 8taj where g is acceleration due to gravity (g =9.8m/s in the metric system or g =32ft/s in the English system). Note, we the parametric equation s of this function can be used to describe the horizontal and vertical position of the projectile. That is, x = (v. cosa ) describes the horizontal position of the projectile and h +(v. cosa) - - gt describes the vertical position of the projectile
