11. Momentum & Impulse

In which of the following processes is the momentum $p$ of the object conserved?

Which statement must be true for the momentum $p$ of a system to be conserved?

A rifle of mass $M$ fires a bullet of mass $m$ with velocity $v$. After firing, which has more momentum: the rifle or the bullet?

In projectile motion, is there any point along the trajectory where the velocity vector $\overrightarrow{v}$ and the acceleration vector $\overrightarrow{a}$ are parallel to each other? If so, where does this occur?

Under which condition is the total momentum $p=\sum p_i$ of a system conserved during a collision?

The conservation of $p$ (momentum) is most closely related to which fundamental principle in physics?

In a closed system, when two objects collide, which physical quantity is always conserved?

Which equation best describes the law of conservation of momentum?

In a closed system where two objects collide and no external forces act, what is the total momentum of the system after the collision?

According to the law of conservation of momentum, what must the total $p$ (momentum) of the system be after two train cars collide in the absence of external forces?

In the context of the conservation of momentum, what is true about the total momentum $p$ of a closed system (one with no external forces acting on it)?

In a closed, isolated system, two objects collide and no external forces act on them. What is the total momentum of the system immediately after the collision?

Two football players collide on a frictionless field and stick together. If the total momentum of the system before the collision is $p_{\mathrm{initial}}$, what is the total momentum of the system immediately after the collision?

Object A moves at 10 m/s at 53° and Object B moves at 5 m/s at –37° as shown below. Calculate the magnitude of the system's total momentum if both objects have a mass of 2kg.

On a frictionless air hockey table, puck A of mass 0.250 kg moves to the right and collides with puck B of mass 0.38kg, which is initially at rest. After the collision, puck A is moving the left at 0.12 m/s and puck B moves to the right at 0.65 m/s. What was the initial velocity of puck A before the collision?
