Question

A partile travel different distances s1&S2 with
different speeds v1&v2in the same direction find
the Ο expression for the average speed
speed.​

Answer 1

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-

$◾</u></em></strong></p><p><strong><em><u>[tex]◾ \bold{average \: speed \: = \frac{total \: distance}{total \: time} }$

◾We need to find the total time taken by both the particles in order to find the average speed.

$\bold{time = \frac{distance}{speed} }$

consider particle 1 -

time taken= S1 / V1

consider particle 2

time taken= S2/ V2

substitute the value in the formula of average speed:

$❐average \: speed = \frac{s1 + s2}{t1 + t2}$

$❐\bold{average \: speed = \frac{s1 + s2}{ \frac{s1}{v1} </u></em></strong><strong><em><u>+</u></em></strong><strong><em><u>\frac{s2}{v2} } }$
