Answer:
☯Given:-
- Initial Speed of Bus (u) = 80 km/h
Multiply by 1000 to convert it into metres,
= 80 × 1000 / 60 × 60
= 22.22 m/s
- Final Speed of Bus (v) = 60 km/h
= 60 × 1000/ 60 × 60
= 16.66 m/s
- Time Taken (t) = 5 s
☯Formula Used :-
Acceleration (a) = v - u/t
Putting Values in the Formula:
a = 16.66 - 22.22/ 5
a = -5.56 /5
a = - 1.11 m/s
Thus,
Acceleration of the bus (Retardation) is -1 .11 m/s².
