Question

Q9. Write the expressions/ formulae to calculate the following: a) Average Speed 1 b) Average Velocity​

Answer 1

Explanation:

Average speed = (2× V1×V2 ) / (V1 +V2)

Average speed =Half of sum of two velocities That is (V1 +V2) / 2

But remember there's only one master formula which gives arise to numerous formulae

And that is Average speed =

( distance covered in given time ) /(time taken)

Cheers!!!

Answer 2

Answer:

\overline{v} = average velocity

{\Delta x} = displacement

{\Delta t} = change in time

Explanation:

What is the formula to calculate average speed? The most common formula for average speed is distance traveled divided by time taken. The other formula, if you have the initial and final speed, add the two together, and divide by 2.
