Question

velocity of a cyclist increase from 5m/sec to 25m/sec in 10sec it's acceleration is​

Answer 1

$\huge\fcolorbox{red}{h}{Question}$

Velocity of a cyclist increase from 5m/sec to 25m/sec in 10sec it's acceleration is.

$\huge\fcolorbox{red}{yellw}{Given}$

• The initial velocity of cycle is 5m/s.
• The final velocity of cycle is 25m/s.
• time taken is 10sec.

$\huge\fcolorbox{red}{yellw}{Formulas}$

• v = u + at
• v² - u² = 2as
• s = ut + 1/2 at²

$\huge\fcolorbox{red}{yello}{Solution}$

u = 5m/s ;v = 25m/s ; t = 5sec ; a = ?

➣ v = u + at

➣ 25 = 5 + 5a

➣ 25 - 5 = 5a

➣ 20 = 5a

➣ a = 20/5

➣ a = 4m/s²

( Or )

➣ a = (v - u)/t

➣ a = (25 - 5)/5

➣ a = 20/5

➣ a = 4m/s²

Answer 2

Explanation:

$\huge\fcolorbox{blue}{green}{Given}$

• The initial velocity of cycle is 5m/s.

• The final velocity of cycle is 25m/s.

• time taken by cyclists is 10sec.

$\huge\fcolorbox{blue}{green}{Formulas used}$

• v = u + at

• v² - u² = 2as

• s = ut + 1/2 at²

$\huge\fcolorbox{blue}{green}{Solution}$

➣ a = (v - u)/t

➣ a = (25 - 5)/10

➣ a = 20/10

➣ a = 2m/s²

( Or ) IT CAN BE:

u = 5m/s ; v = 25m/s ; t = 10sec ; a = ?

➣ v = u + at

➣ 25 = 5 + 10a

➣ 25 - 5 = 10a

➣ 20 = 10a

➣ a = 20/10

➣ a = 2m/s²
