Just multiply the two numbers! That will give you the change in momentum, i.e., the impulse.

The impulse required to produce a velocity change of 4 m/s in a 12 kg mass can be calculated using the impulse-momentum relationship: Impulse = change in momentum.
First, calculate the initial momentum of the mass using the formula: initial momentum = mass x initial velocity. Assuming the initial velocity is 0 m/s, the initial momentum is 0.
Next, calculate the final momentum using the formula: final momentum = mass x final velocity. With the final velocity being 4 m/s, the final momentum is 12 kg x 4 m/s = 48 kg*m/s.
The change in momentum is then the final momentum minus the initial momentum: 48 kgm/s - 0 kgm/s = 48 kg*m/s.
Therefore, the impulse required to produce this velocity change in the 12 kg mass is 48 kg*m/s.

what is the relation of mass and velocity to impulse?
Impulse is equal to the change in momentum of an object, which is the product of its mass and velocity. So, the greater the mass or velocity of an object, the greater the impulse required to change its momentum.
Is impulse delivered to an object equal to a change in the objects velocity?
Yes, impulse is equal to the change in momentum of an object, which can be calculated as the mass of the object multiplied by the change in velocity. So, impulse is related to the change in velocity of an object.
If the velocity is constant does that mean that the impulse is the momentum?
No, constant velocity means there is no change in velocity over time. Impulse is the change in momentum, given by the force applied over a period of time. Momentum is mass times velocity, a vector quantity.
If the velocity is constant does that mean that there is no impulse?
Not necessarily. Impulse Fdt=change in momentum which could be written as mdv (constant mass, velocity changing) or dmv (changing mass, constant velocity - the so-called conveyor belt problem. Imagine a hopper filled with (say) coal is feeding the coal on to a conveyor belt. The mass of the belt increases with time, so a force has to be applied to it to keep it moving at constant velocity.
How much in the impulse increase if an object is doubled?
If the mass of an object is doubled, its impulse will also double if the change in velocity remains the same. Impulse is equal to the change in momentum, so if both mass and velocity double, the impulse will quadruple.

How can you find the value of the impulse?
The value of an impulse is the change in momentum. If the mass remains constant it is the mass times the change in velocity.

How can impulse increase?
Impulse is denoted as a change in momentum. Momentum has the units of kilogram meter per second. Which is mass times velocity. So you can decrease the time and increase the velocity to increase the impulse.

If the mass of an object is doubled, its impulse will also double if the change in velocity remains the same. Impulse is equal to the change in momentum, so if both mass and velocity double, the impulse will quadruple.
How do you impulse?
The impulse of force is commonly used to calculate forces in collisions. Active formula. Impulse = Average force x time = mass x change in velocity

Are impulse and momentum the same thing?
No, impulse and momentum are not the same thing. Momentum is the product of an object's mass and velocity, while impulse is the change in momentum of an object when a force is applied over a period of time. Impulse helps change an object's momentum.
How can impulse be increase?

How is momentum related ito impulse?
Momentum is the product of an object's mass and its velocity. Impulse, on the other hand, is the change in momentum of an object when a force is applied over a period of time. The relationship between momentum and impulse is described by the impulse-momentum theorem, which states that the impulse experienced by an object is equal to the change in its momentum.
