thanks rock.freak667,
I have found the answer it was on a website called http://www.physics247.com/physics-homework-help/friction-and-weight.php" the answer was 0.09 as is shown here:
mu = Ff/Fn
Ff = (ma) - Fengine
mu = ((ma) - Fengine)/-(mg)
mu = ((1400 * 2) - 4000)/-(1400 * 9.81)
mu =...
Homework Statement
What is the coefficient of friction between the road and the wheels of a 1400kg truck accelerating at 2 m/s/s if the force applied by the engine to the wheels is 4000N.
Homework Equations
