Question

If the initial velocity of a projectile be doubled, keeping the angle of projection same, the maximum height reached by it will
A. remain the same
B. be doubled
C. become four times
D. be halved

Answer 1

Correct Answer - C
`H = (u^(2) sin^(2) theta)/(2g) rArr H prop u^(2)`
If intial velocity be doubled, then maximum height reached by the projectile will become four times
