How do you calculate the new velocity so that momentum remains same?
apply conservation of momentum theory- m1v1=m2v2 where m1 is the initial mass, m2 is the final mass, v1 is the initial velocity and v2 is the final velocity.
What equation would you use to find the acceleration of an object of known mass if you also know the initial velocity final velocity and time over which the acceleration occured?
Use the equation a=(v-u)/t, whereby v stands for final velocity, u for initial velocity and t for time.
Is it true that to calculate acceleraltion you need to know both the final and the initial velocity of an object?
No. That's only one of several possibilities. -- with initial velocity, distance, and time, you can calculate acceleration -- with final velocity, distance, and time, you can calculate acceleration -- with force and mass, you can calculate acceleration -- with initial and final momentum, you can calculate acceleration -- with initial and final kinetic energy, you can calculate acceleration -- with mass, velocity at either end, and kinetic energy at the other end, you can calculate acceleration And I'm sure there are several more that I've missed.
How do you work out height from initial velocity final velocity mass and work done?
If you throw an object up, and assume that air resistance is negligible, knowing the initial velocity is enough. One way to do this is to use conservation of energy. Calculate the energy from the initial velocity, then insert it in the formula for gravitational potential energy.Same for final velocity - the final speed is the same as the initial speed. If you know the work done, you already have the first half of the above steps solved.
How do you find final velocity given height and mass?
the final velocity assuming that the mass is falling and that air resistance can be ignored but it is acceleration not mass that is important (can be gravity) final velocity is = ( (starting velocity)2 x 2 x acceleration x height )0.5
How do you find work given mass initial velocity and final velocity?
We assume you mean the work done in order to change the velocity of the moving mass.Easiest way is to calculate the change in the kinetic energy of the moving mass, and realizethat it's equal to the amount of work either put into the motion of the mass or taken out of it.Initial kinetic energy = 1/2 m Vi2Final kinetic energy = 1/2 m Vf2Change in kinetic energy = 1/2 m ( Vf2 - Vi2)
What would you use to find the acceleration?
The answer depends on the context: You can find the acceleration if you know any three of : initial velocity, final velocity, time, distance travelled. You can find it if you know the mass and force. You know the two masses and the distance between them (gravitational acceleration).
Total initial momentum of two objects?
That may vary, depending on the initial velocity and mass.That may vary, depending on the initial velocity and mass.That may vary, depending on the initial velocity and mass.That may vary, depending on the initial velocity and mass.
If two gliders of equal mass and equal and opposite initial velocity collide perfectly elastically what are the final velocities of the gliders in terms of the initial velocities?
Both the gliders will be travelling at exactly the same speed as the initial velocity but in opposite directions.
Does potentail energy have an influence on the final velocity of a falling object?
yes it does. u can calculate the final velocity of the falling object with the following eqn: initial potential energy= final kinetic energy or mgh = 1/2mv2 where m=mass, h = height,v=final velocity
How do you calculate velocity after perfectly collision?
To calculate the velocity after a perfectly elastic collision, you need to apply the principle of conservation of momentum and kinetic energy. First, find the initial momentum of the system before the collision by adding the momenta of the objects involved. Then, find the final momentum after the collision by equating it to the initial momentum. Next, solve for the final velocities of the objects by dividing the final momentum by their respective masses. Finally, make sure to check if the kinetic energy is conserved by comparing the initial and final kinetic energy values.
What is for acceleration?
Acceleration = force / mass The correct equation would be acceleration= the final velocity - the initial velocity divided by time which can be written like this: V (Final speed) - U (Starting speed) ____________________________ T (Time)
