Question

An aeroplane acquires a speed of 1800 km/hr. before it takes off from the runway
which is 5000 meter long what is the acceleration if it is uniform?
2) 2500 m/s2
4) 2.5 m/s2
1) 250 m/s2
3) 25 m/s2​

Answer 1

Answer:

25m/s²

Step-by-step explanation:

u = 0m/s

s = 5000m

Final velocity (v) = 1800km/hr

                           = 1800×5/18m/s

                           = 500m/s

∵ v²= u² +2as

 (500)² = (0)² + 2×a×5000

250000 = 10000×a

⇒ a = 250000/10000

∴ a = 25m/s²
