A 7kg block is pulled at a constant velocity by a horizontal 25 N force

- Calculate normal & gravitational forces
- Calculate the applied & frictional forces
- Calculate the coefficient of friction

CAN SOMEONE PLEASE HELP ME WITH THE EQUATIONS FOR ALL OF THESE THINGS?

Assuming the block is on a horizontal surface.

Vertically (y):
Gravitational force = mg
normal reaction, N = mg
(N is reaction required to remain in equilibrium)

Horizontally (x):
Since block moves with constant velocity, it is in dynamic equilibrium, so for equilibrium,
applied force = frictional forces
Applied force = 25N
frictional force = μkN

These are the necessary equations to find the required values.
So Fg and Fn would be the same?
