How far does a plane fly in 15 seconds while its velocity is increasing from 75 ms to 145 m s at a uniform rate of acceleration?
Donkasponk
If it accelerates from 75 m/s to 145 m/s at a uniform rate, then its average speed during
the acceleration is 0.5(145+75) = 110 m/s.
Distance covered in 15 sec at average speed of 110 m/s = (15 x 110) = 1,650 m = 1.65 km.

What is the Acceleration of a car that got up to 45 ms from a rest position in 3 seconds?
Velocity at time 0 sec = 0m per sec Velocity at time 3 sec = 45m per sec Acceleration is 45/3 = 15m per sec if the acceleration is uniform
When you are comparing equal intervals of time how does the distance change?
The answer depends on whether it is uniform motion, motion under constant acceleration, motion under constantly increasing (decreasing) acceleration, or something else. Since you have not bothered to provide that crucial bit of information, I cannot provide a more useful answer.

What is formula of uniform speed and average speed?
r=d/t is farmula of speed or uniform speed and its si unit is m/s.
How far will an airplane travel before takeoff if the plane can accelerate uniformly at a rate of 2.45 meters per second to its takeoff speed of 70 meters per second?
The first step is to find out how long the airplane took before takeoff. If it travels at a uniform 2.45ms-2 acceleration and needs to get to 70ms-1 then this will take 70/2.45 = 28.57142857... seconds. The next step is to calculate the average speed. The plane starts at 0 and ends at 70, so the average speed will be 35ms-1. To find the distance travelled, we multiply the average speed (35) by the time taken (28.57142857...) and this gives 1,000. Thus, the plane travels for 1km before takeoff.
Are all symmetric distribution are normal?
No. The binomial distribution (discrete) or uniform distribution (discrete or continuous) are symmetrical but they are not normal. There are others.
Can uniform angular velocity has acceleration?
No, uniform angular velocity means no angular acceleration.
What is the difference between increasing velocity and uniform velocity?
Increasing velocity means that the body is accelerating and a force is acting on the body to produce the acceleration. Uniform velocity means that there is no acceleration or deceleration and so no force acts on the body. (Note that in practice we cannot achieve perpetual motion because of either the decelerating force of gravity or friction).
When body have 2ms accleration in 15 seconds with a velocity 30ms does the velocity of the car uniform?
Although the question is stated in a somewhat confusing way, we can state withconfidence that the velocity of the car is NOT uniform, because a value is given forits acceleration. 'Uniform' motion means zero acceleration.
What is the difference between uniform and variable velocity?
Uniform velocity is velocity unaffected by acceleration. Variable velocity is velocity affected by acceleration. Lauren "Physics above all!"
Why is acceleration zero with uniform velocity?
Uniform velocity means the velocity is not changing. Acceleration is defined as the rate of change of velocity. If velocity isn't changing, the rate of change is zero.
How do you find the uniform acceleration if the speed and acceleration are given?
Find out the time using speed and acceleration, (time=speed/acceleration) and then use it to find out uniform velocity. From that find out uniform acceleration. (as uniform acceleration is equal changes of velocity over equal intervals of time)
What is the importance of uniform acceleration graph in physics what is instantaneous velocity?
The slope of a velocity-time graph that shows uniform acceleration is the actual acceleration. Instantaneous velocity is the velocity of a body at a particular moment in time.
When a cars velocity is uniform what it is acceleration?
Acceleration is change of velocity divided by time; so if the velocity doesn't change, acceleration is zero.
Why is the body moving with a uniform velocity is zero?
The body is not zero, but the sum of all forces on it is. -- "Uniform velocity" means no acceleration. -- Acceleration is force/mass . -- If acceleration is zero, that's an indication that force must be zero.
What is the acceleration of vehicle moving with uniform velocity?
It has zero acceleration!!
How the velocity uniform?
"Uniform velocity" means zero acceleration, that is, constant speed in a straight line.rate of change of velocity is zero
What is the Difference between Uniform motion and uniform acceleration?
"Uniform motion" means constant velocity ... constant speed in a straight line. "Acceleration" means any change in velocity ... speed or direction. So 'uniform motion' means zero acceleration.
