Question

Attention plz :)!

The velocity of a body moving at an initial speed of 80 m/s and having an acceleration of 100m/s after 2 s will be​

Answer 1

$\maltese$Given :

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

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

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

$\dashrightarrow\sf\:Acceleration\: of \:Body\: = \:100\: m/s$

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

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

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

$\maltese$ To Find :

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

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

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

$\maltese$ Solution :

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

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

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

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

• 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 !

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

• $:\implies\sf\:V\: =\: 80\: + \:100\:×\: 2$

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

• $:\implies\sf\: V \:=\: 80\: +\: 200\:m/s$

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

• $:\implies\sf\: V\: =\: 280\: m/s$

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

$\blue\maltese$ Therefore :

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

$\leadsto\sf\:Final\:Velocity\:of \:body\: is\:280\:m/s$

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

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 !

$⟹ \: v = \: 80 + 100 \times 2$

$⟹ \: v = 80 + 200 \: m/s$

$v \: = \: 280 \: m/s$

$\bold{ \red{Final \: Velocity \: of \: body \: is \: 280 \: m/s}}$
