a. Derive an expression for the speed of the
bullet-block system as it leaves the table.
b. Derive an expression for the change in
kinetic energy of the bullet-block system
during impact.
c. Find the distance x.
d. Suppose that the bullet passes through the
block instead of being embedded. Is the
distance x for the block would now be greater,
less, or the same from [c]? Why?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd4a97556-9aa9-4435-b9f1-74128ca330cb%2F7c8d147c-b3b8-4ed0-88e8-876a3211ab1d%2F0y75prj_processed.jpeg&w=3840&q=75)
