Question

How much momentum will a object of mass 10 kg transfer to floor if it falls from a height of 5 m?

Answer 1

momemtum=10kg

u=0

v=?

s=5

a=10m/s^2

v^2-u^2=2as

v^2=2as

$v = \sqrt{2as}$

$v = \sqrt{2 \times 10 \times 5}$

$v = \sqrt{100}$

v=10m/s

momentum=mv
=10×10
=100kgm/s
therefore momentum=100kgm/s.
