A projectile is fired at an angle of 60Es to the horizontal with an initial velocity of 800 m/s: (i) Find the time of flight of the projectile before it hits the ground (ii) Find the distance it travels before it hits the ground (range) (iii) Find the time of flight for the projectile to reach its maximum height (iv) Show that the shape of its flight is in the form of a parabola y = bx +cx 2 , where b and c are constants [acceleration due to gravity g = 9.8 m/s2 ]. |
