Question

An object accelerates 7.2 m/s2 when a force of 4.0 newtons is applied to it.

What is the mass of the object?

Answer 1

Answer:

f=m×a then 4=m×7.2 after solving m=0.55 kg

Answer 2

Given:

An object accelerates 7.2 m/s2 when a force of 4.0 newtons is applied to it.

To Find:

The mass of the object.

Solution:

To find the we will follow the following steps:

As we know,

Force is the multiplication of mass and acceleration.

SI unit of force is newton(N) or kgs-².

Force = mass × acceleration

$mass = \frac{force}{accelertion}$

$mass = \frac{4}{7.2}$

$mass = \frac{40}{72} = 0.55 \: kg$

Henceforth, the mass of the object is 0.55 kg.
