Car B is being pushed by a force of 22000 N. If it has a mass of 1375 kg.,
Burka [1]

Answer:

a = 16 m/s²

General Formulas and Concepts:

<u>Dynamics</u>

Newton's Law of Motions

  • Newton's 1st Law of Motion: An object at rest remains at rest and an object in motion stays in motion
  • Newton's 2nd Law of Motion: F = ma (Force is equal to [constant] mass times acceleration)
  • Newton's 3rd Law of Motion: For every action, there is an equal and opposite reaction<u> </u>

Explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

[Given] F = 22000 N

[Given] m = 1375 kg

[Solve] a

<u>Step 2: Find Acceleration</u>

  1. Substitute in variables [Newton's 2nd Law of Motion]:                                 22000 N = (1375 kg)a
  2. Isolate <em>a</em>:                                                                                                            16 m/s² = a
  3. Rewrite:                                                                                                             a = 16 m/s²

What is the force on the book in the figure below ? If the book moves, in which direction will it move ?
olya-2409 [2.1K]

Answer:

1. 2 N to the left

2. To the left.

Explanation:

1. Determination of the net force.

Force applied to the right (Fᵣ) = 18 N

Force applied to the left (Fₗ) = 20 N

Net force (Fₙ) =?

The net force acting on the book can be obtained as follow:

Fₙ = Fₗ – Fᵣ

Fₙ = 20 – 18

Fₙ = 2 N to the left

Thus, the net force acting on the book is 2 N to the left

2. Determination of the direction.

From 1 above, the net force acting on the book is 2 N to the left. This simply means that the book will move to the left direction.
