Question

Find the acceleration gained by a body in 5 sec,if its initial velocity in 20m/s and final velocity is 40m/s.​

Answer 1

Explanation:

Acceleration=

$v2 - v1 \div time$

=>40-20/5sc

So the acceleration is 4m/s.

Hope it will help you.

Plz make it brainlist answer.

Answer 2

$\huge{\underline{\underline{\sf{\green{★Given★}}}}}$

◉ Initial velocity is 20m/s

◉ Final velocity is 40m/s

◉ Time take is 5 sec

$\huge{\underline{\underline{\sf{\green{★To\: Find★}}}}}$

◉ Acceleration of body

$\huge{\underline{\underline{\sf{\green{★Formula\: Used==>}}}}}$

${\underline{\sf{\red{[Acceleration = \: \frac{v - u}{t}]}}}}$

$\huge{\underline{\underline{\sf{\green{★Solution★}}}}}$

[In the given formula, v is final velocity, u is initial velocity and t is time]

Using the given formula of Acceleration =====>

$Acceleration \: = \frac{v - u}{t} \\ \\ = > \frac{40 - 20}{5} \\ \\ = > \frac{20}{5} \\ \\ = > 4m/s2$

Hence, the acceleration is 4m/s²
