∙ 12y agoThe average speed is the distance traveled divided by the time spent traveling.
A car that travels 180 miles in 4 hours did so with an average speed of 180/4 = 45 miles per hour.
A bee that flew 5 meters in 4 seconds did so with an average speed of 5/4 = 1.25 meters per second.
If you need the speed in a different unit, you'll have to convert. The car above also traveled at 45*1.609 = 72.405 kilometers per hour (1 mile = 1.609 kilometers)
A snail crawls across a patio in 4 hours. If the patio is 9 metres across, what is the snails average speed? A: 2.25 metres per second
The formula for speed is speed=distance/time

∙ 8y agoFrom the average acceleration, take the average speed, by doing (V2 - V1)/2. Then, multiply that result by time to get the distance traveled.
If all you are given is average acceleration and nothing else, there is insufficient data to make a calculation.The average acceleration of a rock in earth gravity is about 9.78 m/s2 at the equator. How far will it fall in two seconds? We don't know unless we assume it starts from a standstill or from some other arbitrary spot later on after it was dropped. But that was not specified. The distance the rock falls in a given period of time (which we weren't given) will be different from the distance it falls in the same period of time if the measurement is begun at a different time.

What is average acceleration?
the ratio of the total change in velocity of the object during motion to the total time taken.
is it correct that the average velocity is always equal to the mean value of initial and final velocities?
It is correct only if the object in question is subject to a constant acceleration.
Can an object moving at a constant speed have acceleration?
Acceleration is defined as the change in velocity over a given time period. Velocity is a vector quantity: it includes speed and direction. That being said, you can accelerate an object without changing its speed by simply changing its direction. A body moving along the circumference of a circle its speed may remain a constant, but its velocity will not be a constant since its direction of motion continuously changes, since the velocity changes it has an acceleration.
What is the change in velocity divided by the time interval in which the change occured?
It is acceleration. The difference between final velocity and initial velocity, divided by the time is the AVERAGE acceleration. Remember, though that velocity is a vector. So if you are going round in a circle at a constant speed, your direction of motion is changing continuously and so you are always accelerating!
How Can a body moving with certain velocity in the direction of east have acceleration in the direction of west?
velocity is a vector quantity and also acceleration is a vector quantity. Suppose my automobile is travelling in north direction and I apply brakes to it then until the automobile stops it will move in north direction while the acceleration will act in south direction as brakes are applied.
Is average acceleration equal to instantaneous acceleration for a uniformly accelerated car?
Average acceleration will be equal to instantaneous acceleration when an object has an uniform acceleration throughout its motion. Example : A car accelerating at 1m/s2 uniformly in a straight line.
How do you find average acceleration without knowing the time?
F = MA Force = Mass * AccelerationAcceleration= Force / MassIf you don't know the time, you can find out the force on the object and the mass of the object.
How do you find the mass of an object from it's acceleration?
You cannot is you only know the acceleration
How do you find the acceleration of a object?
Devide velocity of and object over time taken
Suppose that an object is traveling along a straight line Suppose that its velocity function is given by vt equals 4t2 -8t where t is in seconds Find the objects average acceleration along the time?
The object's instantaneous acceleration is (8t - 8) at any time.We can't calculate the average acceleration, because you haven't defined a periodof time over which to average it. We need the start and finish times in order tofind an average.
What would you not use to find the acceleration of an object?
weight
What is the average acceleration of an object due to gravity?
9.81 m/s2
Find average acceleration and instanious acceleration?
average acceleration is the average of the acceleration of a body in its entire motion where as instantaneous acceleration is the rate of change of velocity at an instant. it may be a function of time or velocity or displacement.
How do you find an object's acceleration from it's mass and the force acing on it?
Acceleration = (force) divided by (mass)
How do you find the force of an object with just the mass and angle of object?
You cannot find the force without knowing the velocity or acceleration of the object.
An object has initial velocity in the upward direction a final velocity in the downward direction and undergoes constant acceleration What can you say about its average acceleration?
If, as you say, its acceleration is "constant", then the average is exactly equal to that constant.
To calculate acceleration of an object you must find change in?
velocity
