Finding net force, acceleration and speed.

[amable]

A 150 kg motorcycle starts from rest and accelerates at a constant rate along a a distance of 350m. The applied force is 250 N and the coefficient of kinetic friction is 0.03

Find the net force applied to the motorcycle.
Find the acceleration of the motorcycle.
What is its speed at the end of 350 m?


I tried finding the net force by multiplying mass and gravity, but then I think I'm still wrong.

What forces are acting on the motorcycle?

In what directions are these forces acting?
