Question

A gun fires a bullet at 45° and hits a target 1 km away (same level). The muzzle speed is (g = 10 m/s²):
  1. A
    10 m/s
  2. B
    100 m/s
    Correct
  3. C
    1000 m/s
  4. D
    316 m/s

Correct answer

100 m/s

Explanation

R = u²sin90°/g = u²/g. 1000 = u²/10 → u² = 10000 → u = 100 m/s.
