Kinematics Question 607
Question: The range of a projectile is R when the angle of projection is $ 40{}^\circ $ . For the same velocity of projection and range, the other possible angle of projection is
Options:
A) $ 45{}^\circ $
B)$ 50{}^\circ $
C) $ 60{}^\circ $
D)$ 40{}^\circ $
Show Answer
Answer:
Correct Answer: B
Solution:
[b] Horizontal range R =$ \frac{{{u^{2}}}\sin 2\theta }{\text{g}} $ . Range it’s same for angle of projection $ \theta $ and $ (90{}^\circ -\theta ). $
