A mortar gu, with a maximum range of 20 m on level ground, is placed on the edge of a vertical cliff of height 10 m overlooking a horizontal plane, as illustrated in the following figure. 20 m (a) Consider the sub-problem of the mortar gun on level ground with maximum range of 20 m. Show that the flight time for the projectile on level ground is tf = Hint: The angle required to obtain maximum range is 0 = 7/4. (b) Consider the sub-problem of the mortar gun on level ground with maximum range of 20 m. Show that vo = 2/5g. Hint: The angle required to obtain maximum range is 0 – 1/1.
