2. The attempt at a solution

A)
w=mg
w=48kg*9.8N/kg
w=470.4N

B)
F_x = mg*cos(70)
=48kg*9.8N/kg*cos (70)
=160.88
Is that right​

Looks good to me, but don't forget the units, and you need to note the direction of the force as well as the magnitude.

B)
F_x = mg*cos(70)
=48kg*9.8N/kg*cos (70)
=160.88N(U)
Is that right

How can i ind magnitude direction?

I think it is along the incline in the direction of displacement.
