A projectile is launched with an initial speed of 24 m/s at an angle of 35° above the horizontal. Neglecting air resistance, what is its horizontal range? (g = 9.81 m/s2)

  1. 33.68
  2. 2.3
  3. 110.35
  4. 55.17

Answer

D. 55.17

Solution

Range R = (v02 (2 )) / g = (242 × (70°)) / 9.81 = 55.17 m.
