Question

An object accelerates 5.0 m/s2 when a force of 20.0 newtons is applied to it.
What is the mass of the object? __

Answer 1

Answer:

f=ma

20=5*m

m=20/5

m=4

Answer 2

The mass of the object = 4 kg

Given :

An object accelerates 5.0 m/s² when a force of 20.0 newtons is applied to it.

To find :

The mass of the object

Formula :

Force = mass × acceleration

Solution :

Step 1 of 2 :

Write down force applied and acceleration

Here it is given that an object accelerates 5.0 m/s² when a force of 20.0 newtons is applied to it.

Force applied = F = 20.0 N

Acceleration = a = 5.0 m/s²

Step 2 of 2 :

Calculate the mass of the object

Let mass of the object = m kg

We know that ,

Force = mass × acceleration

⇒ F = ma

⇒ 20 = m × 5

⇒ m = 20/5

⇒ m = 4

Hence mass of the object = 4 kg
