Question

If velocity of a body projected up from the ground is increased by 300%. By
what percentage the maximum height reached increases.​

Answer 1

Answer:

Explanation:

Max height attained by a projectile = $\frac{u^{2} sin^{2}A}{2g}$ , where A is the angle made by the velocity vector with the horizontal.

so , $h_{max}$ $\alpha$ $u^{2}$   (directly proportional)

Since velocity is increased by 300% ... i.e by 3 times ( $u * \frac{300}{100}$ )

so, $h_{max}$ increases by $3^{2}$ times , i.e 9 times .

So , $h_{max}$ increases by 900%  .
