Answer:
D) 1000 m/s
Explanation:
You have the wavelength and frequency, you just need to solve for velocity. You can do this by multiplying each side of the equation by frequency.
Hope this helps.
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 ) .
