Answer:
Retardation = 0.5m/s^2
Explanation:
Given,
Initial Velocity(u) = 54km/h
Initial Velocity(u) = 15m/s
Final Velocity(v) = 36km/h
Final Velocity(v) = 10 m/s
time = 10s
To Find :-
Retardation(-a)
Formula Required :-
Solution :-
a = -0.5 m/s^2
Multiplying with '-' on both sides :-
-a = 0.5 m/s^2
Retardation = -a = 0.5m/s^2
Know More :-
1) v = u + at
2) s = ut + 1/2 at²
3) s = vt - 1/2at²
4) a = v - u/t
5) v²-u² = 2as
