Question

If a rocket is lunched from the ground at 12.6m/s.what's the rockets maximum height

Answer 1

$\red{\boxed{\normal{maximum \: height = \frac{ {u}^{2} }{2g}}}}$

so , by using this formula--

$max. \: height = \frac{ {(12.6)}^{2} }{2g} \\ take \: g = 10m {s}^{ - 2} \\ so \\ max.height = \frac{158.76}{20 } \\ 7.938m$
$\blue{\huge{\boxed{Height=7.938 m}}}$
