Question

A tractor T is pulling two trailers, M₁ and M₂, with a constant acceleration. T has a mass of 200 kg, M₁ has a mass of 100 kg, and M₂ has a mass of 150 kg.If the forward acceleration is 0.60 m/s2, and air resistance is negligible, then the horizontal force on the tractor due to the attachment to M1 is

Answer 1

We will have that the acceleration due to attachment to M1 is:

$a=(100kg)(0.60m/s^2)\Rightarrow a=60N$

So, the acceleration is 60 N.
