Have the answer (in red) just need help working it out please. Question 16

16. A system comprising blocks, a light frictionless pulley, a frictionless incline, and connecting ropes is shown in the figure. The 9.0-kg block accelerates downward when the system is released from rest. Given that g=9.8m/s^2 the tension in the rope connecting the 4.0kg block and the 9.0-kg block is closest to 19.6 N. (B) 1.1 N. (C) 7.1 N. (E) 40.7 N. (F) 55.0 N. The motion diagram shows an object moving along a curved path at constant speed. At which of the points A, C, and E does the object have zero acceleration?

Explanation / Answer

Equations are on 9kg block

9g-T = 9a

on 4 kg block

T-4gsin30=4a

multiplying the first eq with 4 and second with 9 we get

36g - 4T = 9T-18g

54*9.8/13 = T

T = 40.7 N
