Hello everyone, I am having some trouble with some problems. For the first picture I do not understand how to do #19. Please help me! Thank you!(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

Grandma, of weight 500N, exerts a steady horizontal force of 100N on her 700N wing chair, thereby pushing chair across the parlor floor. While Grandma is pushing the chair, her feet do not slip on the floor, and both Grandma and the chair accelerate together at a steady 0.200 m/s^2.

2. Relevant equations

3. The attempt at a solution

For the second picture, I do not know how to solve the last question on resultant force of the traction device that exerts on the foot. Please refer to picture:

For my attempt, I came up with my x and y scalar components and tried adding them but nothing came out to be any of the values. I am just very confused with this problem.
