What else can I help you with?
How do you find final and initial velocities with the average velocity?
You can't.You only know what half the sum of (initial + final) is, (it's the average), but you don't know what the initial and final are.
How do you find final velocity given mass of both objects and there initial velocities and one of their final velocities?
Suppose the two masses are m1 and m2. Their initial velocities are u1 and u2 and final velocities are v1 and v2. Then, using conservation of momentum. m1*u1 + m2*u2 = m1*v1 + m2*v2 Both m1 and m2 are given. Their initial velocities u1 and u2 are given and one of the two final velocities v1 and v2 is given which leaves only one unknown. So substitute all those values and calculate away.
Can the effect of initial velocity on final velocity be predicted?
Well, (final velocity) = (initial velocity) + (acceleration x time)

What is the formula for calculating final velocity when you know the initial speed and the acceleration?
the formula for finding acceleration is final velocity, minus initial velocity, all over time. So if you have the acceleration and initial speed, which is equal to the initial velocity, you must also have time in order to find the final velocity. Once you have the time, you multiply it by the acceleration. That product gives you the difference of the final velocity and initial velocity, so then you just add the initial velocity to the product to find the final velocity.
When is acceleration equals half of the sum of initial and final velocities?
Acceleration is equal to half the sum of initial and final velocities at the midpoint of the motion when the acceleration is constant. This occurs when the object has undergone half of the acceleration time and traveled half of the distance between initial and final velocities.
How do you find final and initial velocities with the average velocity?
You can't.You only know what half the sum of (initial + final) is, (it's the average), but you don't know what the initial and final are.
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?
The final velocities of the gliders after a perfectly elastic collision will also be equal and opposite to their initial velocities. This is due to the conservation of momentum and kinetic energy in elastic collisions.
How do you find final velocity given mass of both objects and there initial velocities and one of their final velocities?
Suppose the two masses are m1 and m2. Their initial velocities are u1 and u2 and final velocities are v1 and v2. Then, using conservation of momentum. m1*u1 + m2*u2 = m1*v1 + m2*v2 Both m1 and m2 are given. Their initial velocities u1 and u2 are given and one of the two final velocities v1 and v2 is given which leaves only one unknown. So substitute all those values and calculate away.
What is the equation for elastic collision and how is it used to calculate the final velocities of two colliding objects?
The equation for elastic collision is: m1u1 m2u2 m1v1 m2v2 where: m1 and m2 are the masses of the two objects u1 and u2 are the initial velocities of the two objects v1 and v2 are the final velocities of the two objects This equation is used to calculate the final velocities of two colliding objects by taking into account their masses and initial velocities. By solving for v1 and v2, we can determine how the velocities of the objects change after the collision while conserving momentum and kinetic energy.
When a rectangle is constructed in order to add perpendicular velocities what part of the rectangle represents the resultant vector?
The diagonal of the rectangle, connecting the initial and final velocities, represents the resultant vector of the perpendicular velocities when constructing a parallelogram of velocities.
What is the final velocity of two objects after an elastic collision?
In an elastic collision, the final velocity of two objects can be calculated using the conservation of momentum and kinetic energy principles. The final velocities depend on the masses and initial velocities of the objects involved in the collision.
What is the elastic collision equation used to calculate the final velocities of two objects after they collide?
The elastic collision equation used to calculate the final velocities of two objects after they collide is: m1u1 m2u2 m1v1 m2v2 where: m1 and m2 are the masses of the two objects, u1 and u2 are the initial velocities of the two objects before the collision, and v1 and v2 are the final velocities of the two objects after the collision.
is it correct that the average velocity is always equal to the mean value of initial and final velocities?
No, the average velocity is calculated as the total displacement divided by the total time taken to travel that distance. It is not simply the mean of the initial and final velocities.
What is the change in velocity for each of the following initial and final velocities?
The change in velocity is the final velocity minus the initial velocity. For example, if the initial velocity is 10 m/s and the final velocity is 20 m/s, the change in velocity is 10 m/s.
What are the physics elastic collision equations used to calculate the final velocities of two objects after they collide?
The physics elastic collision equations used to calculate the final velocities of two objects after they collide are: Conservation of momentum: m1u1 m2u2 m1v1 m2v2 Conservation of kinetic energy: 0.5m1u12 0.5m2u22 0.5m1v12 0.5m2v22 Where: m1 and m2 are the masses of the two objects u1 and u2 are the initial velocities of the two objects v1 and v2 are the final velocities of the two objects
What does it mean when final and initial velocity are the same?
When the final and initial velocities are the same, it means that the object's velocity hasn't changed over time. This could indicate that the object is at rest or moving at a constant speed in a straight line.
