Question

a man moving with 5km/h speed and he travel for 2h .after 2h it acclarate 1m/s^2 then find it final velocity​

Answer 1

Answer:

Explanation:

Solution :-

Here,

We have

Initial velocity, v = 5 km/h = 5 × 5/18 = 1.38 m/s

Time taken, t = 2 h = 2 × 3600 = 7200 seconds

Acceleration, a = 1 m/s²

To Find,

Final velocity, v = ??

We know that,

According to 1st equation of motion,

v = u + at

So,

⇒ v = 1.38 + 1 × 7200

⇒ v = 1.38 + 7200

⇒ v = 7201.38 m/s

Hence, the final velocity of man is 7201.38 m/s.

_______________________________

✰Given:-

⋄ Initial velocity of man (u) = 5km/h= 5 × 5/18= 1.38m/s

⋄ Acceleration of man (a) = 1m/s²

⋄ Time taken (t) = 2h = 2×60×60= 7200s.

✰ To Find:-

⋄ Final velocity of man (v).

✰Solution :-

By using 1st equation of motion

➧ v=u+at

➧ v= 1.38 + 1 × 7200

➧ v= 7201.38 m/s

∴ The final velocity of man is 7201.38 m/s
