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.
Initial velocity is 10 m/s in the direction it was kicked. Final velocity is 0, when friction and air resistance finally causes it to come to a halt.
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.
Well, (final velocity) = (initial velocity) + (acceleration x time)
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.
The final velocity is (the initial velocity) plus (the acceleration multiplied by the time).
The average velocity of a body with non-uniform acceleration can be calculated by taking the average of the initial and final velocities over the time interval. This is done by adding the initial and final velocities and dividing by 2. Mathematically, the formula for average velocity is (v_initial + v_final) / 2.
If you have a particle with constant acceleration, and you add the initial and final velocities and then divide them by two, what you get is the average velocity of the particle in that period of time.
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.
We don't answer questions taken from copyrighted materials.
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.
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.
To find the change in velocity in a given scenario, subtract the initial velocity from the final velocity. The change in velocity is the difference between the two velocities.
Initial velocity is 10 m/s in the direction it was kicked. Final velocity is 0, when friction and air resistance finally causes it to come to a halt.
Is this a question? or a statement that you are unsure of? Well anyways, this would be correct if acceleration was a constant but if acceleration is not a constant, the (not-constant) acceleration would change the rate of velocity and thus that statement/question would be false.
No, It is the average velocity.
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.
To find the acceleration between 25 s and 30 s, you would need to know the initial and final velocities during that time interval. Acceleration is calculated as the change in velocity over time. Once you have the velocities at 25 s and 30 s, you can use the formula: acceleration = (final velocity - initial velocity) / time.
