Answer:
Given
particle 1
distance travelled= s1
speed = v1
particle 2
distance travelled= s2
speed = v2
To Find
Expression for average speed
Solution
❐Formula for average speed-
[tex]◾
[tex]◾ \bold{average \: speed \: = \frac{total \: distance}{total \: time} }[/tex]
◾We need to find the total time taken by both the particles in order to find the average speed.
[tex] \bold{time = \frac{distance}{speed} }[/tex]
consider particle 1 -
time taken= S1 / V1
consider particle 2
time taken= S2/ V2
substitute the value in the formula of average speed:
[tex]❐average \: speed = \frac{s1 + s2}{t1 + t2} [/tex]
[tex] ❐\bold{average \: speed = \frac{s1 + s2}{ \frac{s1}{v1} +\frac{s2}{v2} } }[/tex]
