Question

How much net force is required to accelerate a 1000 kg car at 4.00 m/s2?​

Answer 1

ɢɪᴠᴇɴ :-

• Mass (m) = 1000 kg
• Acceleration (a) = 4 m/s²

ᴛᴏ ғɪɴᴅ :-

• Force (F)

sᴏʟᴜᴛɪᴏɴ :-

We know that,

• Force = mass × acceleration

➮ F = ma

➮ F = 1000 × 4

➮ F = 4000 N

Hence,

• Force (F) is 4000 Newtons

Answer 2

${ \bold{ \text{ \underline{Notations used :-}}}}$

• m = Mass
• a = Acceleration
• f = Force

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

• m = 1000kg
• a = 4.00m/sec^2

${ \bold{ \text{ \underline{To Find:-}}}}$

• f = ??

${ \bold{ \text{ \underline{Solution:-}}}}$

We know that

${ \boxed{ \sf{force = mass \times acceleration}}}$

Or we can write ✍️

F = m × a

By putting given values in above formula we get,

${ \bold{ \sf{ \implies \: f = 1000 \times 4}}}$

${ \bold{ \underline{ \sf{f = 4000N}}}}$

So the net force is required to accelerate a 1000 kg car at 4.00 m/s2 is 4000 N.
