Kinematics Question 679
Question: A projectile fired with initial velocity $ u $ at some angle $ \theta $ has a range $ R $ . If the initial velocity be doubled at the same angle of projection, then the range will be
Options:
A) $ 2R $
B) $ R/2 $
C) $ R $
D) $ 4R $
Show Answer
Answer:
Correct Answer: D
Solution:
[d] $ R=\frac{u^{2}\sin 2\theta }{g}\therefore R\propto u^{2} $ .
If initial velocity be doubled then range will become four times.
