Given that :-
Intial velocity. ,u = 0 m/s
final velocity , v = 54 km /hr
= ( 54 × 5 ) /18 m/s
= 15 m/s
Time , t = 2 min = 2×60 s = 120 second
putting the value
By 2nd equation of motion we know
Hope this helps you

Answer:
Explanation:initial velocity = u = 0
Final velocity = v = 54
Acceleration = change in velocity/ time
= V-U/t
= 54 - 0/ 2
27m/s^2
