Question

a bomb of mass 2m explodes in two equal parts with velocity v in east direction show that other part will move in west with same velocity
sorry I putted wrong value ​

Answer 1

Answer:

Correct option is

A

m−m′mv

(A)m−m1mv

Here we can conserve the momentum 

So 

mv=m1(0)+m−m1(v1)

mv=m−m1(v1)

v1=m−m1mv 

Explanation:

Correct option is

A

m−m′mv

(A)m−m1mv

Here we can conserve the momentum 

So 

mv=m1(0)+m−m1(v1)

mv=m−m1(v1)

v1=m−m1mv 

Answer 2

Answer:

Answer

Correct option is

A

m−m′mv

(A)m−m1mv

Here we can conserve the momentum 

So 

mv=m1(0)+m−m1(v1)

mv=m−m1(v1)

v1=m−m1mv
