Question

An object is initially at rest and after some time it's velocity is 80 m/s and the acceleration is
4m/s2 find the time in which the object achieves this acceleration. pls gI've Step by step answers!!. ​

Answer 1

Answer:

acceleration=velocity/time

Time=velocity/acceleration

Time=80/4=20sec

Answer 2

Question:-

An object is initially at rest and after some time it's velocity is 80 m/s and the acceleration is 4m/s²find the time in which the object achieves this acceleration.

Answer:-

• The time taken by object is 20 seconds.

Solution:-

• Initial velocity (u) = 0m/s
• Final velocity (v) = 80 m/s
• Acceleration (a) = 4 m/s²
• Time taken (t) = ?

$\blue{ \boxed { \huge{ \orange{ a = \frac{v - u}{t} }}}}$

$\large{ : \implies \: \frac{80 - 0}{t} = 4}$

$\large{ : \implies \: 4\times t = 80}$

$\large{ : \implies \: t = \frac{80}{4} }$

$\large{ : \implies \: t = 20 \: s}$

• The time taken by object is 20 seconds.
