Question
A bullet of mass 0.018 kg traveling horizontally at a high speed of 200 m/s embeds itself in a block of mass 4 kg that is sitting at rest on a nearly frictionless surface.
(a) What is the speed of the block after the bullet embeds itself in the block?
Vf = 7
X m/s
(b) Calculate the total translational kinetic energy before and after the collision.
Ktrans,/ = 180
X J
Ktrans,f = 260
X J
(c) Compare the two results and explain why there is a difference.
O The Energy Principle isn't valid for an inelastic collision.
The internal energy of the block-bullet system has increased.
O Some of the momentum is lost in an inelastic collision.
