Impulse = constant force (f) for limited time interval (t)
From force (f) = mass (m) * acceleration (a) (but (a) = velocity change (vc) / time (t))
So: f = m * vc / t
Then: f * t (impulse) = m * vc
So if you know the mass and the required velocity change, you have the value of the impulse.
Say you have a 10 kg mass @ 10 metres / second and want to halve its velocity
(vc = - 5 metres / sec)
So: required impulse = 10 * -5 = -50 n.s

Check in example: -100 newtons for 0.5 seconds (time is always positive) on 10 kg mass, what is the final velocity ? (should be 5 m/s)
>
With mass of 10 kg, acceleration = force / mass = -100 / 10 = -10 (m/s)/s
u = 10 m/s
v = ?
a = -10 (m/s)/s
t = 0.5 seconds
Using: v = u + (a * t), then v = 10 + - 5 , so v = 5 metres / sec
What else can I help you with?
When the force and time of contact are halved the impulse on an object is?
The impulse on an object will be reduced by half when both the force and the time of contact are halved. Impulse is the product of force and time, so decreasing both will result in a proportional decrease in the impulse.
What will happen to the wavelength associated with a moving particle if its velocity is reduced to half?
If the velocity of a moving particle is reduced to half, the wavelength associated with it will remain the same. The wavelength of a particle is determined by its momentum, not its velocity.
Where must the average velocity for an interval be plotted on a velocity-time graph to represent an instantaneous velocity?
The average velocity for an interval must be plotted at the middle of the time interval to represent an instantaneous velocity on a velocity-time graph.
What is the velocity of a ball dropped on the surface of Mars if the acceleration of gravity is 3.7 meters per second squared?
When given a constant acceleration, just multiply it by time, t, to detemine the final velocity. If the initial velocity was zero (as is the case when you drop something), then the average velocity is half the terminal velocity.
If the velocity and frequency of the wave are both reduced to one half the wavelength is?
If the velocity and frequency of the wave are both reduced to one half, the wavelength of the wave remains unchanged. The wavelength of a wave is determined by the velocity and frequency, so if both are reduced by the same factor, the wavelength will remain constant.
When the force and time of contact are halved the impulse on an object is?
The impulse on an object will be reduced by half when both the force and the time of contact are halved. Impulse is the product of force and time, so decreasing both will result in a proportional decrease in the impulse.
When substrate concentration is equal to km what will be the initial velocity?
When the substrate concentration is equal to the Michaelis constant (Km), the initial velocity of the enzyme-catalyzed reaction will be half of the maximum velocity (Vmax) of the reaction. At Km, half of the enzyme active sites are filled with substrate, leading to half of maximum velocity being reached.
What will happen to the wavelength associated with a moving particle if its velocity is reduced to half?
If the velocity of a moving particle is reduced to half, the wavelength associated with it will remain the same. The wavelength of a particle is determined by its momentum, not its velocity.
What is the mass of an object multiplied by its velocity?
The product of an object's mass and velocity is known as momentum. Momentum is defined as mass times velocity and is a vector quantity, meaning it has both magnitude and direction. It is often denoted by the symbol "p."
How can you bind impulse 101 to the mouse in Half Life?
To bind the impulse 101 command to a mouse button in Half-Life, you first need to open the console using the "~" key, then type in "bind mouse3 impulse 101" to bind the command to the middle mouse button (mouse3). You can replace "mouse3" with a different button number to bind it to a different mouse button.
Where must the average velocity for an interval be plotted on a velocity-time graph to represent an instantaneous velocity?
The average velocity for an interval must be plotted at the middle of the time interval to represent an instantaneous velocity on a velocity-time graph.
Is there a source mod for half-life 2 that acts like gta in any way like gta city 17 or something?
no why would u ask that :)
What is the velocity of a ball dropped on the surface of Mars if the acceleration of gravity is 3.7 meters per second squared?
When given a constant acceleration, just multiply it by time, t, to detemine the final velocity. If the initial velocity was zero (as is the case when you drop something), then the average velocity is half the terminal velocity.
How much is a half of a half?
Half would be 50% of something. So half of half would be 25% of something.
How does the kinetic energy of a body change if its momentum is halved?
Since momentum is proportional to the velocity, half the momentum means half the velocity (and therefore half the speed). And since kinetic energy is proportional to the SQUARE of the speed, half the speed means 1/4 the kinetic energy.
What height will it gain after the escape velocity becomes half?
That will depend not only on the escape velocity, but also - very importantly - on the object's speed.
Why velocity is double during circular motion?
This is called the law of astronomic diversion. Gaining energy from falling: half of the energy is diverted and half is potentionally gained. Yet the astronomical law is that falling to a gravitational centrum: half of the gained energy is given to the surroundings ( in form of heat or other) and half of it is gained as potential mechanical Galileian/Newtonian energy. So: a=v^2/r is the changement to velocity = versnelling per radius If a= gM/r then object resides. The free area for energy is from half escape velocity to a full escape velocity for molecules. Hidrogen escapes (while escape velocity earth= 11 km / sec)
