Answer:
1st car acc = 10ms , 2nd car acc = 20
Explanation:
1st car
Given
initial velocity = 0
final velocity = 18 kmph
time =0.5s
a=v-u/t
= (18x 5/18)/0.5
=5/0.5
a = 10
2nd car
GIven
initial velocity = 0
final velocity = 36 kmph
time =0.5s
a=v-u/t
= (36 x 5/18) / 0.5
=10/0.5
a = 20
Hope u are satisfied . if yes click thanks button
