Question

A chettah start from rest and accelerate at 2m/s for 10s calculate the final velocity

Answer 1

$\huge\underline{\overline{\mid{\bold{\orange{Answer-}}\mid}}}$

Given-

Initial velocity = 0m/s

acceleration = 2m/s^2

time= 10s

Find-final velocity = ??

Solution-

$\huge\underline{\overline{\mid{\bold{\blue{ a=\dfrac{v-u}{t}}}\mid}}}$

$2= \dfrac{v- 0 }{10}$

$2\times 10= v$

$v= 20m/s$

Answer 2

Answer

Final velocity = 20 m/s

Given

A cheetah start from rest and accelerate at 2 m/s² for 10 s

To Find

Final velocity

Concept Used

We need to apply equation's of motion

→ v = u + at

→ s = ut + ¹/₂ at²

→ v² - u² = 2as

Solution

Initial velocity , u = 0 m/s

Acceleration , a = 2 m/s²

Time , t = 10 s

Final velocity , v = ? m/s

Apply 1st equation of motion ,

⇒ v = u + at

⇒ v = (0) + (2)(10)

⇒ v = 0 + 20

⇒ v = 20 m/s

So , Final velocity = 20 m/s
