Q1. If a car which is at rest suddenly accelerates at 24km/hr. after travelling for 6 hrs. What will be its final velocity?.please help |
| Answer» 144 km/hExplanation: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 × TV = 0 + 24 × 6V = 144 km/hConclusion:-The final velocity which accelerates by 24 km/h² will have final velocity of 144 km/h after 6 hours. | |
