Question

How much momentum will a mass of 10 kg transfer to floor if it falls from a height of 80m?g= 10m/s

Answer 1

HOLA!!!

_____________________________

HERE IS YOUR ANSWER

GIVEN

Mass (m) = 10kg

Height (h)= 80m

g = 10m/s

momentum (P ) = ?

SOLUTION

we know

P = mv

By given data, m = 10kg

But what about v = ?

We know that

$v = \sqrt{2gh} \\ \: v \:= \: \sqrt{2 \times 10 \times 80} \\ v \: = \sqrt{1600} \\ v \: = \: {40ms}^{ - 1}$
So,

P = mv

= 10 × 40

P = 400kgms^-1
