Problem: Which statement must be true for the momentum of a system to be conserved?a. The net external force on the system is non-zero.b. There are no external forces acting on the system.c. The internal forces sum to zero.d. The net external force on the system is zero.

FREE Expert Solution

Force and momentum are related by the equation:

F=dpdt

When the momentum is conserved, the change in momentum, dp = 0.
