Question

Calculate the maximum height attained by the body thrown vertically upward with a velocity of 19.6 m/s . (g= 9.8 m/s² )​

Answer 1

Given:

$\sf{Initial \:Velocity(u)=19.6}{m{{s}^{-1}}}$

$\sf{Acceleration \:due \:to \:Gravity(g)=9.8m}{{s}^{-2}}$

Solution:

$\sf{At \:maximum \:height \:final \:velocity(v)=0}$

$\sf{{v}^2}={{{u}^2}-2gh}$

$\sf{h={\dfrac{{u}^2}{2g}}}$

$\sf{h={\dfrac{{19.6}^2}{{2}\times{9.8}}}}$

$\sf{h=19.6m}$

$\sf{Thus \:maximum \:height \:attained = \:19.6m}$

Answer 2

The term sublimation is the passage or the transformation or conversion that substances undergo when passing from one state to another, for example from a solid substance to gas. We can define sublimation as the transition of a substance from the solid phase to the gaseous phase without changing into the liquid phase.
