Answer 1

Heyyy mate!!!!
Here is ur answer

Hope this helps u Please make me as a brainliest

Answer 2

here your answer
initial velocity =18km/h
change in m/s= 18×5/18
=5m/s
final velocity =54km /h
change in m/s =54×5/18
15m/s
acceleration =final velocity - initial velocity
= v-u/t
( 15-5)/10
10/10
1m/s square
