A car accelerates at 1.20m/ [forward]. The net force on the car is 1560N [forward].What is the mass of the car?

Question

Answer 1

Using Newton's law F = ma (note 1N = 1kgm/s²)

we know the acceleration is 1.2m/s² and F =1560 N both in the forward direction.

Thus m = F/a = 1560/1.2 = 1300 kg

Answer 2

You need to use Newton's 2nd Law

F = ma. you have everything you need so just rearrange and solve for mass

m =F/a
