1. The problem statement, all variables and given/known data Q.1 Describe a device which can have Kinetic Energy but no linear momentum. Q.2 Is it possible to invent a device with linear momentum and no kinetic energy. 2. Relevant equations p = mv Ek = ½ mv² 3. The attempt at a solution For a "device" to have no linear momentum p = 0, right? But if p = 0 wouldn't Ek just = 0? So would such a "device" be impossible and the answer to Q.2 is no it is not possible.
