Part C, D, G and B

Please check the image that I attached.

-Part B

A chair of mass 15.5 kg$kg$ is sitting on the horizontal floor; the floor provides a friction force of 11.5 N$N$ . You push on the chair with a force F$F\text{F}$ = 37.0 N$N$ that is directed at an angle of 36.0 ∘${}^{\circ }$ below the horizontal and the chair slides along the floor.

B: What is the magnitude of the acceleration of the chair???

-Part C and D

In the situation shown in the figure, a person is pulling with a constant, nonzero force 26.5 N$N$ on string 1, which is attached to block A with mass 3.40 kg$kg$ . Block A is also attached to block B (mass 5.80 kg$kg$ ) via string 2, as shown.

For this problem, assume that neither string stretches and that friction is negligible.

C: What is the acceleration of the blocks?

D: What is the tension in string 2?

-Part G

Now consider a block being pushed up a smooth slope. The force pushing the block is parallel to the slope. (Figure 4) Which of the following forces are acting on the block?

weight

friction

force of push

normal force
