Kinematics Question 680

Question: If the initial velocity of a projectile be doubled, keeping the angle of projection same, the maximum height reached by it will

Options:

A) Remain the same

B) Be doubled

C) Be quadrupled

D) Be halved

Show Answer

Answer:

Correct Answer: C

Solution:

[c] $ H=\frac{u^{2}{{\sin }^{2}}\theta }{2g}\therefore H\propto u^{2}. $

If initial velocity be doubled then maximum height reached by the projectile will quadrupled.
