Problem

A fixed mortar fires a bomb at an angle of

53^\circ

above the horizontal with a muzzle velocity of

80\,\mathrm{m\,s^{-1}}

. A tank is advancing directly towards the mortar on level ground at a constant speed of

5\,\mathrm{m\,s^{-1}}

. The initial separation between the mortar and tank, at the instant the mortar is fired, so that the tank would be hit is, taking

g=10\,\mathrm{m\,s^{-2}}

, (1)

662.4\,\mathrm{m}

(2)

526.3\,\mathrm{m}

(3)

486.6\,\mathrm{m}

(4) None of these
