Answer:
force acting on the parent = 25 N .
Explanation:
According to third law of Newton , there is equal and opposite reaction to every action . Here force by the parent on child is action and the force by child on parent is reaction . The former is given as 25 N so force by child on parent will also be 25 N .
Answer is 25 N .
IF the bag is suspended freely in mid-air and free to move
without friction, then the linear momentum is the same both
before and after the hit.
Momentum of the bullet before the hit = ( m₁ v₁ ).
Momentum of the (bullet + bag) after the hit = (m₁ + m₂) (v₂) .
Momentum is conserved, so we can say that ...
( m₁ v₁ ) = (m₁ + m₂) (v₂)
v₂ = ( m₁ v₁ ) / (m₁ + m₂)
Usually the mass of the bag is much much more than the mass
of the bullet, so the mass of the bullet can be ignored after the
hit, and the formula is very closely ...
v₂ = v₁ ( m₁ / m₂ ) .
