Answer:
for this ques u can apply 1st eq of motion
v=u+at
from this u got
a=4m/s^2

Here,
u (initial velocity) = 120m/s
v (final velocity) = 600m/s
t (time) = 2minutes = 120s
[1 min = 60s]
[2min = 2*60 = 120s]
a = v-u/t
a = 600-120/120
Acceleration = 4m/s^2
u (initial velocity) = 120m/s
v (final velocity) = 600m/s
t (time) = 2minutes = 120s
[1 min = 60s]
[2min = 2*60 = 120s]
a = v-u/t
a = 600-120/120
Acceleration = 4m/s^2
