Kinematics Question 682
Question: The range of a projectile for a given initial velocity is maximum when the angle of projection is $ 45^{o} $ . The range will be minimum, if the angle of projection is
Options:
A) $ 90^{o} $
B) $ 180^{o} $
C) $ 60^{o} $
D) $ 75^{o} $
Show Answer
Answer:
Correct Answer: A
Solution:
[a] Range$ =\frac{u^{2}\sin 2\theta }{g} $ ; when $ \theta =90{}^\circ $ , $ R=0 $ i.e. the body will fall at the point of projection after completing one dimensional motion under gravity.
