yep,initial momentum = final

ok, so try applying total initial momentum = total final momentum to rubber bouncing off a wall on ice (ie, no foundations, so the wall can slide along the ice, but the wall is initially stationary)

<h2>1. What is the difference between impulse and momentum?</h2><p>Impulse and momentum are both physical quantities that describe the motion of an object. However, impulse is the change in momentum over a certain period of time, while momentum is the product of an object's mass and velocity. In other words, impulse is a force acting on an object for a specific amount of time, while momentum is a measure of an object's inertia and how difficult it is to change its motion.</p><h2>2. How are impulse and momentum related?</h2><p>Impulse and momentum are closely related through Newton's Second Law of Motion, which states that the net force acting on an object is equal to the rate of change of its momentum. This means that the impulse acting on an object is equal to the change in its momentum. In mathematical terms, impulse (J) is equal to the change in momentum (Δp), or J = Δp.</p><h2>3. What is an example of impulse and momentum in everyday life?</h2><p>One example of impulse and momentum in everyday life is a game of billiards. When a cue ball strikes a stationary ball, the cue ball's momentum is transferred to the stationary ball, causing it to move. The force of the cue ball acting on the stationary ball for a short period of time is the impulse that changes the stationary ball's momentum, causing it to move in a different direction.</p><h2>4. How does impulse affect the motion of an object?</h2><p>Impulse can affect the motion of an object in several ways. If a large impulse is applied to an object over a short period of time, it can cause a significant change in the object's momentum and therefore its motion. On the other hand, a smaller impulse applied over a longer period of time may result in a smaller change in momentum and a slower change in motion. Additionally, an impulse applied in the opposite direction of an object's motion can cause it to slow down or even change direction.</p><h2>5. What is the unit of measurement for impulse and momentum?</h2><p>In the SI system, impulse is measured in Newton-seconds (N·s) and momentum is measured in kilogram-meters per second (kg·m/s). In the English system, impulse is measured in pound-seconds (lb·s) and momentum is measured in slug-feet per second (slug·ft/s). These units can also be expressed as force multiplied by time (N·s = kg·m/s) and mass multiplied by velocity (kg·m/s = kg·m/s).</p>
