Hi.
I found this question:
A ball is suspended by a string and a bullet is shot at it from underneath.Given the masses and velocity of the bullet,can we conserve the momentum for this inelastic collision?
My doubt is isn't there a vertical downward external force acting on the system(gravity).
But my textbook has conserved the momentum and got the answer.How?
And for a box moving on a surface which meets another box on a surface with lot of friction?Can we conserve momentum here,for this collision?
Thank You
