Using newton's second law, F = ma, the answer is -2.5 m/s^2.
4520 = (1800)(a)
electromagnetic waves do not need any medium to travel but mechanical waves require a medium to travel regardless the state of matter that it is in (solid, liquid, gas)
Copper is a metal but it is not magnetic like a magnet
Answer:
Explanation:
Since the surface is frictionless, momentum will be conserved. If the bullet of mass has an initial velocity and a final velocity and the block of mass has an initial velocity and a final velocity then the initial and final momentum of the system will be:
Since momentum is conserved, , which means:
We know that the block is brought to rest by the collision, which means and leaves us with:
which is the same as:
Considering the direction the bullet moves initially as the positive one, and writing in S.I., this gives us:
So kinetic energy of the bullet as it emerges from the block will be:
