Answer:

Heyaa♡♡

Here is the answer .

Hope it helped you.

Answer 2

$\huge\boxed{\fcolorbox{black}{cyan}{Solution }}$

★ Given :

M1=50 kg

m2=300 kg

v1= 3 m/s

v2=?

★ To Find :

Conservation of momentum.

= m1+v1+m2v2+0

0 is because no initial velocity is applied and the answer will be 

• 50 x 3 + 300v2=0
• i.e v2 = -150/300=-0.5m/s

★ So , it is moving backward direction the velocity (v2) will be 0.5m/s in the backward direction.
