Question

How much momentum of body mass10kg transfer it if fell down from height 80cm?

Answer 1

The velocity of the body after falling from height 80 cm is found using,

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

Substituting numerical values,

$v^2=0^2+2(9.81)(0.8)\\ v=3.962$

The momentum transferred is

$mv=10(3.962)=39.62 \;kgm/s$
