Best Answer:  8.075*10^3 NewtonsSource(s):Newton's Second Law of Motion P=MA

Answer:

Magnitude of force is \(F=8.1\times 10^3\ N\)

Explanation:

It is given that,

Acceleration of car, \(a=4.75\ m\s^2\)

Mass of car, \(m=1.7\times 10^3\ kg\)

We have to find magnitude of force. It is given by using Newton's second law of motion which states that force is given by the product of mass and acceleration :

F = m a

\(F=1.7\times 10^3\ kg\times 4.75\ m/s^2\)

\(F=8.075\times 10^3\ N\)

or

\(F=8.1\times 10^3\ N\)

Hence, the correct option is (c)
