ANSWER

V

1

=15m/s,t

1

=2s,v

2

=5m/s,t

2

=8s

Speed of the particle for 2s is 15m/s

Distance=speed×time,d=30m

The Speed of the particle for next 8s is 5m/s

Distance=Speed×time,d=40m

Average speed =

8+2

40+30

=7m/s

hope my answer helps u please follow me and mark me as Brainliest....

Answer 2

Answer:

Average speed - 4.16 m/s

Average velocity- 3m/s north-east
