Question

a body covers 40 metre in 20 second and next 80 metres in 20 seconds find the average velocity

Answer 1

@
average velocity = (v+u)/2
=> (40/20+80/20)/2
=(4/2+8/2)/2
=(12/2)/2
=12/4
=3
average velocity= 3m/s

Answer 2

Heyaa folk!!

AS GIVEN :-

u = 40 meter , t = 20 sec

v = 80 Meter , t = 20 sec

we know Av = v + u / 2

=>. 80/20+40/20/2

=> 8/2+4/2/2

=> 6/ 2

=> 3 m/s
