Answer:

2 is this answer for ur question mark me brainlist and follow me

Answer 2

Explanation:

Initial velocity=0km/h

Final velocity =80km/h

Time=20 min

fisrt convert 80 km/h into m/s

=80*5/18

=22.2 m/s

then convert 20 minutes into seconds

= 20*60

=1200 seconds

a=v-u/t

a=(22.2-0)/1200

a=0.0185 m/s²
