1. u = 5 m/s
a = 2 m/s²
t = 5 s
2. v = u + at
= 5 + 2 × 5
= 15m/s
= 15 × 18 / 5
[ m/s × 18 / 5 → km/hr]
= 6 km/hr

Given:
- Initial speed, u = 5 m/s
- Acceleration, a = 2 m/s²
To Find:
- Final velocity of the car after 5 seconds in km/hr.
Solution:
To find velocity of the car after 5 seconds in km/hr = ?
We know that,
V = u + at
→ V = 5 + 2×5
→ V = 2 + 10
→ V = 15 m/s
Convert m/s into km/hr.
→ 15 × 5/18
→ 4.16 km/hr.
Therefore,
Final velocity of the car after 5 seconds is 4.16 km/hr.
