Question

what is the net force required to give an automobile with a mass of 1,600 kg an acceleration of 4.5m/s

Answer 1

Hi there!

Recall Newton's Second Law:

`\large\boxed{\Sigma F = ma}}`

∑F = Net force (N)

m = mass (kg)

a = acceleration (m/s²)

We are already given the mass and acceleration, so we can plug these values into the equation:

∑F = 1600 · 4.5 = 7200 N
