Question

3. Law of Acceleration: A 1400 kg car has an acceleration of 3.6 m/s^2. What is the net force applied by the engine?

Answer 1

ANSWER:

5040 N

STEP-BY-STEP EXPLANATION:

We have that the force can be calculated as follows:

$F=m\cdot a$

We know the mass and the acceleration, so we plug in and calculate the force, just like this:

$\begin{gathered} m=1400\text{ kg; a = 3.6}\frac{m}{s^2} \\ F=1400\cdot3.6 \\ F=5040\text{ N} \end{gathered}$
