Question

You push on a box with 100 N of force, causing it to accelerate at 5 m/s?.

What must the mass of the box be?

Answer 1

Given:-

Force,F = 100 N

Acceleration,a = 5 m/s²

To be calculated:-

Calculate the mass of the box .

Formula used:-

`\bf \: Force = Mass * Acceleration`

Solution:-

`\sf \: Force = Mass × Acceleration`

★ Substituting the values in the above formula,we get:

`\sf \implies \: 100 = Mass * 5`

`\sf \implies \: Mass = \cancel(100)/(5)`

`\sf \implies \: Mass = 20 \: kg`

Answer 2

We are given with the amount of force applied and accleration of a certain body and we have to find the mass of the box.

• Force applied = 100 N
• Accleration = 5 m/s²

According to Netwon's 2nd law,

After deriving, we will get that

• Force = Mass × Accleration

Plugging the given values to get mass,

➝ 100 N = Mass × 5 m/s²

➝ Mass = 100 / 5 kg

➝ Mass = 20 kg

Thus, the required mass of the box is 20 kg.
