Will you settle for average speed ?
The general method for solving any problem is to use what you do know in order
to find the answer. Generally, you never use something you don't know, right ?
Well, you told us what you don't have, but neglected to mention what you do have.
If you know starting and ending speed, then average speed = 1/2 (starting speed + ending speed).
If you know distance and acceleration, then time = sqrt( 2 x distance / acceleration).
Then you have time and distance, and you can find average speed.

Average time people stay in a job?
A report from 2012 showed that the average time people stayed at a job was 4.4 years. A report from 2013 showed people stay an average of 4.6 years at a job.
What is the formula for computing acceleration?
a = Δv/Δt also: a = Δv/t Δ = Stands for Delta v = Stands for Velocity t = Stands for Time a = Stands for Acceleration / = Stands for Division (Divide)
What is visual voice mail?
visual voicemail is a voicemail that you can check on the screen of your phone without putting it to your ear and listening. its really simple to do also, without the time of regular voicemail :-)
Which piece of technology would you have the easy time doing without?
TV computer cell phone i pod
What two pieces of information are required to calculate average velocity?
Time and velocity
What is instantaneous velocity of a body in terms of its average velocity?
The instantaneous velocity is the limit of the average velocity, as the time interval tends to zero. If you are not familiar with limits, basically you make the time interval very small and calculate the average velocity.
How do calculate average velocity?
Divide the net displacement by the time of travel.
Can calculate average acceleration of an obj ect given change in velocity with respect to time?
Acceleration is the derivative of the velocity expression. If you have an equation for velocity, simply take the derivative of it and you will have an equation for the average acceleration.
How is the velocity-time graph related to the distance traveled?
The product of velocity and time yields distance travelled if the velocity is constant for the time in question. If velocity is not constant, one must first calculate the average velocity over a given time period before multiplying it by the time involved.
Calculate average velocity and average speed?
sharon sprinter changes her speed from 4.5m/s to 7.5m/s in the middle 1.5 seconds of a 100m race. what is her average velocity for this time period?
How do you calculate magnitude of acceleration without time?
vf2 = vi2 + 2ad, where vf is final velocity, vi is initial velocity, a is acceleration, and d is displacement. Solve for a. vf2 = vi2 + 2ad vf2 - vi2 = 2ad (vf2 - vi2)/2d = a
What is the formula used to calculate the velocity of an object?
The average velocity in a particular direction = distance travelled in that direction / time taken. Velocity is a vector so the direction is important. If I go from A to B and then return to A my average velocity will be zero. My speed, on the other hand, will not be zero.
How can you get average velocity?
You can calculate average speed by dividing the total distance travelled by the total time of travel. To go from speed to velocity, you would also need to determine the vector (direction of travel).
How can you calculate the rockets average velocity?
You calculate a rockets average velocity the same way you calculate the average velocity of anything else, a car, a running dog, or a stick floating on a stream. Velocity equals distance divided by time. It does not matter if your rocket traveled five thousand kilometers in one hour or if your car traveled 30 miles in one hour even if it stopped for gas along the way, you use the same formula.
Why can you only calculate a stone's average speed during its fall?
That is just not true! If you can calculate its average speed you should be able to calculate its speed at any point in time during its flight, including its final velocity.
What is average velocity?
Average velocity is def.ined as the ratio of total displacement to total time taken.
