ok, thank you! so i set up the incline to be the xaxis. now, the force of gravity is found by f = mg ((8000)(9.8) = 78400 so 78400 sin 4 = 5468.9 which is the x component of the gravity force? so, does f_net=ma mean 40000 is the total force so i subtract gravity force and friction to find what...

The forces are normal, gravity, friction, and the trucks excretion on the road, normal and gravity cancel, so i need to incorporate friction? another thought, 5500N cos 4 and 5500N sin 4 give me x and y components of friction, I am just thinking about how to apply this to the equation.

Homework Statement A truck of mass 8000 kg is accelerating at 5.0 m/s2 up a hill of inclination 4 degrees to the horizontal The friction forces on the truck add up to 5500 N. What force does the truck exert against the road in the direction of travel? What force does the road exert on...
