Question

The velocity of a body moving at an initial speed of 80 m/s and having an acceleration of
4m/s after 2 s will be​

Answer 1

$\red\dag$Given :

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

$\dashrightarrow\sf\:Initial\: Speed\: of\: Body\: =\: 80 \:m/s$

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

$\dashrightarrow\sf\:Acceleration\: of \:Body\: = \:4\: m/s$

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

$\dashrightarrow\sf\: Time \:taken \:=\: 2S$

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

$\blue\dag$ To Find :

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

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

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

$\pink\dag$ Solution :

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

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

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

$\large\underline{\pink{\mathfrak \purple{\dag} Understanding\: the \: Concept:-}}$

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 !

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

• $\dashrightarrow\sf\:V\: =\: 80\: + \:4\:×\: 2$

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

• $\dashrightarrow\sf\: V \:=\: 80\: +\: 8\:m/s$

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

• $\dashrightarrow\sf\: V\: =\: 88\: m/s$

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

$\red\maltese$ Therefore :

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

$\leadsto\sf\:Final\:Velocity\:of \:body\: is\:88\:m/s$

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

Answer 2

According to Question :

$\dashrightarrow\:V \:=\: u\: +\: at$

$\leadsto\sf\: V \:=\: 80\: +\: 8\:m/s$

$\leadsto\sf\: V\: =\: 88\: m/s$

• Velocity = 88 m/s
