4. A car has a mass of 1,350 kg. A driver travels on a level road with an acceleration of 4.7 m/s.What force, neglecting friction, must be exerted to achieve this accelerations?

Respuesta :

We have to use Newton's Second Law

[tex]F=ma[/tex]

Where m = 1,350 kg and a = 4.7 m/s2.

[tex]\begin{gathered} F=1,350\operatorname{kg}\cdot\frac{4.7m}{s^2} \\ F=6,345N \end{gathered}[/tex]

Hence, the force exerted is 6,345 Newtons.
