SUMMARY

The problem involves calculating the force a painter must apply to a pulley system to ascend with an acceleration of 0.2 m/s². Given the painter's mass of 70 kg and the chair's mass of 10 kg, the equation used is ((Ms - Mm)/(Ms + Mm)) * X = 0.2, where X represents the force applied. The gravitational force (g) must be considered in the calculations, as it affects the total weight of the system. Properly identifying all forces acting on the combined mass of the painter and chair is crucial for accurate results.

PREREQUISITES

this is a problem i have gotten on my homework, but this problem is giving me a bit of trouble does anyone know the best way to approch it? i was using ((Ms - Mm)/(Ms+Mm))* X = 0.2
X being the force he must pull down on

A house painter uses the chair and pulley arrangement of the figure to lift himself up the side of a house. The painter's mass is 70 kg and the chair's mass is 10 kg. With what force must he pull down on the rope in order to accelerate upward at .2 m/s

been trying to work on this, i was wondering should g be a factor in the equation?
 
Since you did not include the figure, I can only make a guess as to the problem. I assume the painter is pulling himself up via a pulley and rope.

As always, identify all the forces acting on the "painter + chair" (treat them as a unit). Note that the painter pulls down on one end of the rope, but both ends of the rope pull up on him.
