Question

A motorcycle accelerates uniformly from 10m/s to 20m/s in 12s . calculate acceleration.​

Answer 1

Given

• Initial velocity (u) = 10m/s
• Final velocity (v) = 20m/s
• Time taken (t) = 12s

To find

• Acceleration = ?

Solution

As we know that

→ v = u + at

→ 20 = 10 + a × 12

→ 20 - 10 = 12a

→ 10 = 12a

→ a = 10/12 = 5/6 m/s²

Hence,

• Acceleration of motorcycle is 5/6m/s²

Extra Information

• Force = mass × acceleration
• v = u + at {First equation of motion}
• s = ut + ½ at² {Second equation of motion}
• v² = u² + 2as {third equation of motion}
• Pressure = Force/Area

━━━━━━━━━━━━━━━━━━━━

✰✰ ANSWER ✰✰

$\longmapsto\tt{Initial\:Velocity(u)=10m/s}$

$\longmapsto\tt{Final\:Velocity(v)=20m/s}$

$\longmapsto\tt{Time\:Taken(t)=12sec}$

➥Using Formula : -

$\longmapsto\tt{\small{\boxed{\bold{\bold{\red{\sf{a=\dfrac{v-u}{t}}}}}}}}$

➥Putting Values : -

$\longmapsto\tt{a=\dfrac{20-10}{12}}$

$\longmapsto\tt{a=\cancel\dfrac{10}{12}}$

$\longmapsto\tt\boxed{a=0.8{m/s}^{2}}$

☛So , Acceleration is 0.8 m/s²..

★Acceleration : -

Acceleration is defined as the rate of change of velocity of an object.In S.I system it is measured in m/s²..It is usually denoted by a..

Formula of Acceleration is : -

$\longmapsto\tt\boxed{a=\dfrac{v-u}{t}}$
