Answer:
0.20
Explanation:
intial velocity=0
final velocity=90km,convert it into m\s i.e.90*5/18=25m/s
time=2min i.e.2*60=120s
according To the formula v=u+at
25=0+a(120)
25/120=a
0.20 =a

Answer:
initial velocity (v) -0 because body starts from rest
final velocity (u) -90
acceleration- v-u/t
0-90/2= 90/2 =45
45m/s^2
