This year, there has been many treats to world peace because of missile tests. Missiles differ from usual projectile motion because there is an additional propelling force on the missile. We will do a basic analysis of missiles. Here we will regard the missile as a point object. 180 160- 140- 120 Figure 2(bi) Height in m 100- 80- 60+ 40- 20- Figure 2(bii) 1000 2000 3000 4000 5000 6000 Horizontal distance in m Figure 2(c) As shown in Figure 2(bi), if the missile is projected horizontally from a cliff of height 180 m but the propulsion is not turned on, the position of the missile is given in Figure 2(c) at intervals of 1 s for the first 6 s. i. However, usually fuel is burnt to propel the missile as shown in Figure 2(bii). If the propulsion provides a constant acceleration of 40 m/s², determine the angle o such that the missile will fly at a constant height.
