A particle moves in the east direction with15 m/sec
for 2 sec then northwards with 5 m/s for 8 sec.
Average velocity of the particle is :-
(1) 1 m/s
(2) 5 m/s
(3) 7 m/s
(4) 10 m/s​

Answer 1

(4) 10m/s

average velocity = u+v/2

= 15+5/2=20/2=10m/s

Answer 2

I show u a picture plzzz ....if i am correct plzz follow me and mark.as brainliest answer
