━━━━━━━━━━━━━━━━━━━━

✰✰ ANSWER ✰✰

$\longmapsto\tt{Acceleration = 2cm}$

$\longmapsto\tt{Time = 3s}$

➥Using 1st Eq. of Motion : -

$\longmapsto\tt{\small{\boxed{\bold{\bold{\red{\sf{v=u+at}}}}}}}$

➙Putting Values : -

$\longmapsto\tt{v = (0)+(2)\times{3}}$

$\longmapsto\tt{v = 0 + 6}$

$\longmapsto\tt{6cm/s}$

━━━━━━━━━━━━━━━━━━━━

✔Equations Of Motion : -

• v = u + at
• v² - u ² = 2as
• s = ut + 1/2 at²
