Question

An object with a mass of 2.0 kg accelerates at 2.0 m/s^2 when an unknown force is applied to it. What is the amount of the force?

GIVEN:

REQUIRED:

EQUATION:

SOLUTION:

ANSWER:

Answer 1

ANSWER: 4.0 N

Step-by-step explanation

The formula for Newton's second law is

`F = ma`

where:

• F = force
• m = mass
• a = acceleration

Given:

mass (m) = 2.0 kg

acceleration (a) =
`2.0` m/
`s^2`

Required:

F = ?

Equation:

F = ma

Solution:

F = 2.0 x 2.0

Answer:

F = 4.0 N
