Asked Question :-


A bus moves from rest to a speed of 900m/s in 25seconds. What is the magnitude of bus acceleration?
​

Answer 1

$\red\bigstar$Given :

$:\mapsto$ Initial velocity of Bus (u) = 0

$:\mapsto$ Final velocity of Bus (v) = 900m/s

$:\mapsto$ Time taken by Bus (T) = 25sec

$\;\;$

$\pink\bigstar$Need to FinD :

$:\implies$ Magnitude of Bus acceleration?

$\;\;$

$\green\bigstar$Formula Used Here :

• $:\mapsto$v = u + at

$\red\dag$Where :

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

$\purple\maltese$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 Bus !

$\;\;$

$\red\dag$Putting value in formula :

$\qquad\twoheadrightarrow$v = u + at

$\qquad\twoheadrightarrow$900m/s = 0 + a × 25s

$\qquad\twoheadrightarrow$900= 0 + 25a

$\qquad\twoheadrightarrow$900= 25a

$\qquad\twoheadrightarrow$a = 36 m/s²

$\;\;$

$\orange\maltese$ Therefore :

$:\red\longmapsto$ Acceleration of Bus is 36 m/s²

Answer 2

Explanation:

★ Given :

↦ Initial velocity of Bus (u) = 0

↦ Final velocity of Bus (v) = 900m/s

↦ Time taken by Bus (T) = 25sec
