Chapter 7 - Linear Momentum - Questions: 19

Answer

Two equal-mass clay blobs that initially have equal and opposite momenta, colliding head-on, will come to a dead stop and all of the initial kinetic energy is lost.

Work Step by Step

The initial momentum of the system is zero, so the final momentum is zero. The blobs stick together, so the final momentum can be zero only if the combined blob is stationary.
