A particle of mass 8kg is pulled along a rough horizontal plane by a horizontal force of 50N. The coefficient of friction between the particle and the plane is 0.6. Find the acceleration of the particle.
Answer is 0.37, Can I have someone just lay out how you get there? To help me understand.

SOLUTION.
Acceleration of a object or a particle of some mass is the Ration of net force acting over it with the mass of the particle/Object.
ACC to your question....
F = 50N
force of friction = μmg
Where m is the mass of the body
g is acceleration due to gravity
μ is coefficient of friction
Net Force = F - μmg
Net force = 50 - 0.6×8×9.8
Net Force = 50 - 47.04
Net force = 2.96N
ACC to Newton's law....
Net force = mass × Acceleration
2.96 = 8 × Acceleration
Acceleration = 0.37m/sec²
