Physics Two Dimensional Motion Question 122
Question: A body is projected from the ground with a velocity at an angle of $ 30{}^\circ $ . It crosses a wall after 3 sec. How far beyond the wall the stone will strike the ground?
[Take $ \text{g =10 m/}{{\text{s}}^{\text{2}}} $ ]
Options:
A) 50\sqrt{2} B)70$ \sqrt{2} $ C) 15$ \sqrt{3} $ D)16$ \sqrt{2} $
Show Answer
Answer:
Correct Answer: A
Solution:
Required distance from the wall $ =\frac{{{\text{u}}^{\text{2}}}\sin 2\theta }{\text{g}}-\text{u cos}\theta \times \text{t}=50\sqrt{3},\text{m} $
