AnshikaGupta2004 The ability to keep increasing or developing; the force that makes something move faster and faster

Given,

Initial velocity, u = 0m/s

Mass, m = 4kg

Height, s = 100m

Acceleration, a= 9.8m/s^2

Final velocity, v = ?

v^2 = u^2 + 2as

=> v^2 = 0 + 2*100*9.8

=> v^2 = 1960

=> v = 44.27m/s

So, final velocity when it touches the ground will be 44.27m/s.

SinisterChill 1.The product of mass and Velocity is called momentum.
2.The formula of momentum is
$p = mv$
3.Momentum is a vector quantity.
4.It's SI unit is kg-ms.
