Question

A cars engine supplies 6445 N A force to get a car going. If the car is mass is 1040 kg what is the cars acceleration round to the nearest tenth

Answer 1

Newton's second law relates the force with the mass and the acceleration in the following way:

`F=ma`

In this case the force is 6445 N and the mass is 1040 kg, plugging these values in the equation above and solving for a we have:

`\begin{gathered} 1040a=6445 \\ a=(6445)/(1040) \\ a=6.2 \end{gathered}`

Therefore, the acceleration of the car is 6.2 meters per second per second.
