Question

A battery-powered lawn mower has a mass of 52.0 kg. If the net external force on the lawn

mower, including both your push and any resistance, is 44.5 N (about 10 pounds), then what
will be the magnitude of the mower's acceleration?

Answer 1

Hi there!

We can use the equation:

∑F = ma, where:

∑F = net force (N)

m = mass (kg)

a = acceleration (m/s²)

Rearrange in terms of acceleration:

∑F/m = a

Plug in the given values:

44.5/52 = 0.856 m/s²
