If a body starts with a velocity of 2 ms and moves with an acceleration of 5 ms - then what will be the distance travelled in 5 second?

$\large{ \dag{ \bold{ \green{ \underline{ \underline{Answer...}}}}}}$

$\large{ \sf{distance \: travelled \: by \: body = 72.5 \: m}}$

$\large{ \dag{ \bold{ \red{ \underline{ \underline{Solution...}}}}}}$

$\sf{ \star{ \purple{ \underline{ \underline{given...}}}}}$

• Started with velocity=2 m/s
• Body acclerating at the rate of 5 m/s^2
• Time taken by the body = 5 sec

$\sf{ \star{ \purple{ \underline{ \underline{to \: find...}}}}}$

• Distance travelled by the body...

$\large{ \bold{ \pink{ \underline{ \underline{according \: to \: question...}}}}}$

$\large{ \sf{ \implies{initial \: velocity = 2 \: ms {}^{ - 1} }}} \\ \\ \large{ \sf{ \implies{accleration = 5 \: ms {}^{ - 1} }}} \\ \\ \large{ \sf{ \implies{time \: taken = 5 \: sec}}} \\ \\ \large{ \red{ \sf{u \: must \: know...2nd\: equation \: of \: motion}}} \\ \large{ \boxed{ \sf{ \green{s = ut + \frac{1}{2} a {t}^{2} }}}} \\ \\ \large{ \sf{ \red{by \: using \: formula....}}} \\ \\ \large{ \sf{ \implies{s = 2 \times 5 + \frac{1}{2} \times 5 \times (5) {}^{2} }}} \\ \\ \large{ \sf{ \implies{s = 10 + \frac{125}{2} \: }}} \\ \\ \large{ \sf{ \implies{s = 10 + 62.5 \: }}} \\ \\ \large{ \sf{ \implies{ \boxed{ \purple{ s = 72.5 \: m}}}}}$

$\large{ \bold{ \orange{required \: answer \: is \: 72.5 \: m}}}$

3 equations of motion...

• v = u + at

• v² = u² + 2as

• s = ut + ½at²
