F = 13 N

<h3>Further explanation</h3>

Given

Acceleration= a = 2.6 m/s²

Required

Force

Solution

Newton's second law :

ΣF = m x a

The wheeled cart used in the experiment is the same, so the mass used is the same

We use one of the data for example data 1 to find mass :

F = 1 N, a = 0.2 m/s²

m = F/a

m = 1/0.2

m = 5 kg

so for acceleration= a = 2.6 m/s² :

F = 5 kg x 2.6 m/s²

F = 13 N
