Physics Question :-

Train moves from rest to a speed of 50 m/s in 25 seconds. What is the magnitude of its acceleration?​

Answer 1

★ Given :

• » Initial velocity of train (u) = 0
• » Final velocity of train (v) = 50m/s
• » Time taken by train (T) = 25sec

★ Need to Find :

• » Acceleration of the train ?

★ Formula Used Here :

• » v = u + at

______________

⌬ Where :

• ⟹ v = Final velocity
• ⟹ u = Initial velocity
• ⟹ a = acceleration
• ⟹ t = Time taken

______________

❍ Understanding the concept :

• ➣ For solving this question whe have to apply 1st equation of motion. After putting value in formula we can easily calculate the acceleration of train !

⌬ Putting value in formula :

• ➮ v = u + at
• ➮ 50m/s = 0 + a × 25s
• ➮ 50= 0 + 25a
• ➮ 50= 25a
• ➮ a = 2 m/s²

❒ Therefore :

• ⪼ Acceleration of train is 2m/s²

━━━━━━━━━━━━━━━━

Answer 2

Answer will be 2 m/s²
