bekas [8.4K]

Answer:

\displaystyle F = 150 \ N

General Formulas and Concepts:

<u>Dynamics</u>

  • Newton's Second Law of Motion:                                                                       \displaystyle \sum F = ma

Explanation:

We are given the following variables:

m = 50 kg

a = 3 m/s²

To find the object's force, we use Newton's Second Law of Motion. Plug in your variables into the equation:

F = (50 kg)(3 m/s²)

F = 150 kg · m/s²

F = 150 N
