At what angle should a body be projected with a velocity 24 ~ms ⁻¹ just to pass over the obstacle 14 m high at a distance of 24 m . [Take g =10 ~ms ⁻² ]

Options

  1. A=1
  2. B=2
  3. C=3
  4. D=19 / 5

Correct answer

D. =19 / 5

Step-by-step solution

x=24=u . t t= 24 24 = 1 y=14=u t- 1 2 g t^2 14= u - 5 ^2 aligned & 14=u -5 ^2 & 5 ^2 -24 +19=0 & =1,19 / 5 . Ans aligned
