Homework Statement
The 10-Mg truck hauls the 20-Mg trailer. If the unit starts from rest on a level road with a tractive force f of 20 kN between the driving wheels of the truck and the road, compute the tension T in the horizontal drawbar and the acceleration a of the rig.
Homework Equations
Did i do my sum of forces correctly? If so, I have two unknowns and one equation. The sum of forces in the y - direction would not help. Do i use constant acceleration formulas? If so, i can't seem to figure out which one to use.
The Attempt at a Solution
F_x = ma_x
ma_x = T - f
[(20+10)*10^3]*a_x = T - 20,000
