Question

How much momentum will an object of mass 10 kg is transfer to the floor if it fall from a height of 5m (g=10m s-2)

Answer 1

Assuming It is an Inelastic collision.
Momentum = mv -0= 10*(2*10*5)^1/2= 100 kg-m/s

Answer 2

Hi friend,

We know that ,

S=1/2 at²

t²= 2S/a

t²= 1

t= 1 sec.

:- v= 10m/s

Momentum (p)= MV

P= 10×10

P=100 Kg m/s.

Hope this helped you a little!!!
