Question

The maximum height attained by a projectile is increased by 5%.
Keeping the angle of projection constant, what is the percentage
increase in horizontal range?
​

Answer 1

Explanation:

If h is the maximum height attained by the projectile,

then $\binom{{u}^{2} { \sin }^{2} 0}{2g} or \: \: \: \: \: r = \binom{ {u}^{2} \sin20 }{g}$

[tex]\binom{R}{h}{=}\binom{2\sin0\cos0}[\tex
