Question

You push on a box with 100 N of force, causing it to accelerate at 5 m/s2.

Answer 1

Given:

Force,F = 100 N

Acceleration,a = 5 m/s²

To be calculated:-

Calculate the mass of a box.

Solution:-

$\bf \: Force = Mass × Acceleration$

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

$\sf \implies \: 100 = m \times 5$

$\sf \implies \: m = \cancel \dfrac{100}{5}$

$\sf \implies \: Mass(m) = 2 \: kg$

Thus,the mass of a box is 2 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.
