Answer:
144 km/h
Explanation:
Given:-
A car in rest position.(∴ U = 0)
Acceleration = 24 km/h² (A)
Time = 6 hours. (T)
To find:-
Final velocity after the time given (V)
Solution:-
(By first kinematical equation)
V = U + A × T
V = 0 + 24 × 6
V = 144 km/h
Conclusion:-
The final velocity which accelerates by 24 km/h² will have final velocity of 144 km/h after 6 hours.
