A 3.00 kg mass is initially at rest upon a horizontal surface. An applied force of 25.0 N directed at an angle of -15° relative to the +x direction acts on the mass.

What is the normal force acting on the mass?

What is the net force acting on the mass if the system is frictionless?

What is the acceleration of the mass?

If friction is introduced into the system and the acceleration of the mass is measured to be 5.00 m/s2 i , what is the coefficient of kinetic friction?

If the object is displaced 2.00 m in the +x direction while the applied force and friction act, what is the object's change in kinetic energy?

Do you have a picture just to make sure I'm picturing it correctly?
