Time of Flight, Maximum Height & Range

The maximum range of a gun of horizontal terrain is 16 km. If g=10 m s−2g = 10\text{ m s}^{-2}, then muzzle velocity of a shell must be

Show answer and solution

Answer: (c)

  1. Rmax=u2g⇒u2=16000×10=1.6×105R_{max} = \frac{u^2}{g} \Rightarrow u^2 = 16000 \times 10 = 1.6 \times 10^5
  2. u=400 m s−1u = 400\text{ m s}^{-1}
  3. So the answer is (c).
