Question

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

Answer 1

Answer:

To find the time it takes to stop, you use the same equation, this time with v = 20 m/s,

v2f−v2i=2ad to find a, and then solve for time.

Answer 2

$\huge\bold{\underline{\underline{{Given:-}}}}$

Initial velocity (u) = 10m/s

Final velocity (v) = 20m/s

Time taken (t) = 12s

$\huge\bold{\underline {\underline{{To \: find:-}}}}$

Acceleration = ?

$\huge{\boxed{\rm{\red{Solution:-}}}}$

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

Acceleration of motorcycle is 5/6m/s²Acceleration of motorcycle is 5/6m/s²Extra 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
