Explanation:
Given that :-
Intial velocity V1 = 45 km/hr = 12.5 m/s
Final velocity V2 = 0 m/s
Time t = 30sec.
We know that Acceleration is :-
Change in the velocity ∆V (V2 - V1)
=> A = -------------------------------------------------
Change in Time ∆T ( T2 - T1)
Acceleration = (0 - 45) / 30
Acceleration = -1.5 m/sec^2 ✅
( -ive sign comes because there is retardation in this question ❓)
