Question

An artillery shell is fired at an angle of 31.6 degrees abovethe horizontal ground with an initial speed of 1980 m/s. The acceleration of gravity is 9.8 m/s2. Find the total time of flight of the shell neglecting airresistance Answer in min. Find its horizontal range, neglecting air resistance. Answer in units of km.

Explanation / Answer

   a.   Total time offlight      T   =   2* u * sin / g   =   2 * 1980 *sin 31.60 /9.8   =   211.73   s    b.   Range   R   =   u2* sin 2 /g   =   19802 * sin 2 *31.60 / 9.8   =   3.57 *105   m       R   =   357   km
