Question

And object, as a mass of 500 g
is moving with lom/s is added
with another mass of 250g. Find
its new velcoity?​

Answer 1

Answer:

in this question momentum conservation will be applied

Explanation:

for 1st object

mv=0.5kg × 10m/s=5kgm/s

now finally

m'v'=(0.5+0.25)v'=0.75v'kgm/s

now equate both equation

5=0.75v'

v'=20/3 m/s
