Question

The velocity of a body moving at an initial speed of 20 m/s and having an acceleration of
40 m/s after 10 s will be​

Answer 1

$\red\dag$Given :

$\:\:\:\:\:\:\:\:\:\:\:$

$\longrightarrow\sf\:Initial\: Speed\: of\: Body\: =\: 20 \:m/s$

$\:\:\:\:\:\:\:\:\:\:\:$

$\longrightarrow\sf\:Acceleration\: of \:Body\: = \:40\: m/s$

$\:\:\:\:\:\:\:\:\:\:\:$

$\longrightarrow\sf\: Time \:taken \:=\: 10S$

$\:\:\:\:\:\:\:\:\:\:\:$

$\blue\dag$ To Find :

$\:\:\:\:\:\:\:\:\:\:\:$

• $\leadsto\sf\: Final \:Velocity\: of \:Body$

$\:\:\:\:\:\:\:\:\:\:\:$

$\pink\dag$ Solution :

$\:\:\:\:\:\:\:\:\:\:\:$

$\large\underline{\orange{\sf \blue{\maltese} Formula \: :-\: v\: = \:u\: +at\::-}}$

$\:\:\:\:\:\:\:\:\:\:\:$

$\large\underline{\red{\sf \purple{\dag} Understanding\: the \: Concept:-}}$

• For solving this question we have to just apply one formula of motion ( v = u + at ), after putting value in formula we can get final answer . So Finally solving further.

• By using Formula !

$\:\:\:\:\:\:\:\:\:\:\:$

• $\longrightarrow\sf\:V\: =\: 20\: + \:40\:×\: 10$

$\:\:\:\:\:\:\:\:\:\:\:$

• $\longrightarrow\sf\: V \:=\: 20\: +\: 400\:m/s$

$\:\:\:\:\:\:\:\:\:\:\:$

• $\longrightarrow\sf\: V\: =\: 420\: m/s$

$\:\:\:\:\:\:\:\:\:\:\:$

$\red\maltese$ Therefore :

$\:\:\:\:\:\:\:\:\:\:\:$

$\leadsto\sf\:Final\:Velocity\:of \:body\: is\:420\:m/s$

$\:\:\:\:\:\:\:\:\:\:\:$

Answer 2

$\huge\boxed{\fcolorbox{purple}{ink}{GIVEN:}}$

• Initial Speed(u)→20m/s

• acceleration (a)=40m/s²

• Time=10sec.

$\huge\boxed{\fcolorbox{pink}{ink}{TO FIND:}}$

• Final Velocity=?

$\huge\boxed{\fcolorbox{red}{ink}{SOLUTION:}}$

Since,

We know that,

__________________________

v=u+at

__________________________

Therefore,By substituting the values

v=20+(40)×10

: . v=20+400

: . v=420m/s

: . The final Velocity of the body is 420m/s.
