Question

A bike moves from rest to a speed of 250 m/s in 25 seconds. What is the magnitude of bike acceleration?

# No spam answer :)!​

Answer 1

★ Given :

• ⇒ Initial velocity of Bike (u) = 0
• ⇒ Final velocity of Bike (v) = 250m/s
• ⇒ Time taken by Bike (T) = 25sec

★ Need to FinD :

• ⪼ Magnitude of bike acceleration?

★ 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 Bike !

⌬ Putting value in formula :

• ➟ v = u + at
• ➟ 250m/s = 0 + a × 25s
• ➟ 250= 0 + 25a
• ➟ 250= 25a
• ➟ a = 10 m/s²

✠ Therefore :

• ➮ Acceleration of Bike is 10m/s²
