A body of mass 5 kg is dropped from a height of 100m. With what velocity it will hit the ground? (Take g=10 m/s²)

Solution

Given,

Mass of the body, m = 5 kg
Height from where the mass is dropped = 100 m
Acceleartion due to gravity, g = 10 m/s²

Using the formula,

v²-u²= 2as
Here,
u = 0,

a = g = 10 m/s²,

s = 100m

$∴ v^{2} - (0)^{2} = 2 \times 10 \times 100 = 2000$

$\Rightarrow$ v = 44.72 m/s, is the velocity with the body will hit the ground.
