What is the average velocity of an object that goes from 25 meters per sec to 65 meters per sec?

We lack the time this acceleration is being made. 25 to 65 can be done in one second or in one year.

When is average speed of an object not equal to average velocity?
For example, an object goes in a circle, at a speed of 50 km/hour. The average speed is 50 km/hour; the average velocity is zero.
A squirrel drops a nut over a cliff what is the velocity of the nut after 3 seconds?
Ignoring air resistance, the velocity of any object that goes off a cliff is 29.4 meters (96.5 feet) per second downward, after 3 seconds in free-fall.
What happens to an object in free fall can it has a constant velocity?
No, due to acceleration its velocity goes on increasing. It is given as v = g t
What do you understand by channel of constant velocity?
The channel of constant velocity means that it is moving along a straigh line, and as every second of time goes by, the object travels through the same number of meters or we can say that it travels equal displacements per equal time intervals. Y.N.Rajesh........................
What is meant by centripetal acceleration is perpendicular to velocity?
As an object goes round in a circular path, then its velocity will along the tangent at that instant. But centripetal acceleration is normal to that tangent and so along the radius of curvature. As acceleration is perpendicular to the velocity, the direction aspect is ever changing and so the object goes round the circular path.
Why does terminal velocity exist?
When an object is falling, it accelerates, so it is speeding up. The faster it goes, the more air resistance there is on the object. Eventually, the force of the air resistance pushing up on the object will equal the force of gravity pushing down on the object. The forces on the object are balanced (they cancel out), so it will have no acceleration. This causes terminal velocity; the object is not speeding up anymore. When the forces on an object are balanced, it has no acceleration. This does not mean it has no velocity, it just means that the velocity is not changing (it does not speed up or slow down.)
A balls is thrown upwards with a velocity of 10 ms How high does it go?
The ball goes up 5.1 meters.
The velocity of an object goes from 4 m per second to 12 m per second in 4 seconds what is its acceleration?
The change in velocity was 8 m / s. Divide that by 4 seconds and get 2 m / s2 -- sometimes stated as acceleration of 2 meters per second per second.
What is termanal velocity?
Perhaps you mean terminal velocity. This is the maximum velocity reached by an object falling to the ground when the acceleration due to gravity is matched by the drag resistance of the air through which it is falling.
What happens to kinetic energy of an object if the velocity is doubled?
If the speed of an object doubles, its kinetic energy quadruples. This is because velocity is squared in the formula for kinetic energy.
What is the velocity of a freely falling object 6 seconds after being dropped?
The acceleration of gravity is 9.8 meters/sec2 .After 6 seconds, the object's speed is (6 x 9.8) = 58.8 meters/sec .It's velocity is 58.8 meters per second downward.
A plane goes from a velocity of 28 ms to -45 ms in 12 seconds What is his average acceleration?
