Question

Please show a visual and explain the different forces that are accounted for. I am unsure of why certain forces are included in sum of Fx and sum of Fy, plain explain and show steps.

4. A string attached to the block in the figure is exerting a force
F = 300 N. The block is moving up the incline. The mass of the block is 40 kg, and the coefficient of kinetic friction is 0.10. The angle between the ramp and the floor is 25 degrees. What is the approximate acceleration of the block, in m/s2?

(a) 0.8
(b) 1.7
(c) 2.5
(d) 3.1
(e) none of these
