Question
Two model rockets, as shown in Figure 5, are fired simultaneously from a ledge with the heights of h = 100 m with initial velocities of Von = V = 200 m/s, at initial angles of 0 = 45° and 0в = 75° with respect to the horizontal. Determine: (a) The time when the projectile A will reach the position that forms an angle a = 20° below the horizontal. (b) The velocity of projectile A at this instant. (c) The velocity of projectile B at this instant and its angle with horizontal. (d) The relative velocity of projectile A with respect to B at this instant. (e) Which of the rockets will hit the ground first? Note: please consider everything. And show step by step working out!. On occasions I recieve wrong answers!. So kindly please double check the final answers!.
