Question

a body is free falling from height 90 M. find velocity at mid point of journey. g=10ms​

Answer 1

Answer:

Explanation:

Given,

Height(h) = 90m

Gravitation(g) = 10m/s^2

To Find :-

Velocity at the mid-point of the journey

Formula Used :-

$v=\sqrt{2g\dfrac{h}{2}}$

Solution :-

$v=\sqrt{2\times 10\times \dfrac{90}{2}}$

$=\sqrt{20\times45}$

$= \sqrt{900}$

v = 30 m/s

velocity at mid - point = 30 m/s
