<u>Answer:</u>
0.5 ms−2
<u>Explanation</u>:
Newton's second law of motion is mathematically expressed as
F = ma ; where F is the force exerted on an object, m is the mass of the object, and a is the acceleration of that object.
In this case, the mass of the car and the force exerted on it are provided as information.
Let's plug in the values into the formula
F = ma :
⇒600
N =1200
kg × a
Let's express N
using SI base units:
⇒600 kg m s−2 = 1200 kg × a
⇒600 kg m s−2 = 1200 kg = 1200 kg
1200 kg × a
⇒1 on 2 ms −2 = 1 × a
∴ a = 0.5 ms−2
Therefore, the acceleration of the car is
0.5 ms−2
when its engine exerts a force of 600N
