Question

How much momentum will an object of mass 10kg transfer to the floor if it falls from a height 5m ( g=10m). please send me answer fast and right answer with full explanation​​

Answer 1

Explanation:

given:-

mass=10kg

height=5m

g=10m/s^2

momentum=mass*velocity

p=m*v

as we know,

$v^{2} = {u}^{2} + 2gh$

${v}^{2} = 0 + 2 \times 10 \times 5$

${v}^{2} = 100$

${v} = 100m s ^{ - 2}$

$p = mv$

$p = 10 \times 10$

$p = 100kg.m {s}^{ - 2}$

so, the momentum is 100kg.m/s^2
