acceleration =change in velocity
______________
time
therefor 33-15=18/20
=0•9

SillySam:
km/hr will change to m/sec bro
yes
u didn't
i forfet it
so now edit it

Initial velocity (u)=15km/hr
= 15×18/5
= 18×3 m/sec
=54m/sec
Final velocity (v)= 33km/hr
= 33 ×18/5
= 594/5 m/sec
Time =20 sec
Acceleration =v-u/t
=594/5-54/20
=324/5/20
=324/100
=3.24 m/sec^2
