1. The problem statement, all variables and given/known data Find the Acceleration of the system and the tensions in the three ropes. *If you can't see the picture there's a triangle (ABC), a train of four objects and three pulleys (one exactly at each corner). Side AC (hypotenuse) at the bottom, side AB to the left and side AC to the right. Angle A=37 Angle B=53 Angle C=90 There is only kinetic friction between A and B of 0.125. mass A= 10kg (hangs straight off the pulley at Angle A) mass B= 5kg (on AB) mass C= 10kg (on BC) mass D= 20kg (hanging off the pulley at Angle C) Up is positive 2. Relevant equations 3. The attempt at a solution I got an acceleration of 28.96m/s/s but I'm fairly sure it's wrong lol. I used these equations using scalar values: m1: Fnet= T1 - Fg 10a= T1 - (10)(10) T1= 10a+ 100 m2: Fnet= T2 -T1 - Fres - Fg// 5a= T2 - T1 - (0.125)(50cos37) - 50sin37 T2= T1 + 5a + 35.08 m3: Fnet= T3 + Fg// - T2 10a= T3 + 100sin53 - T2 T3= T2 + 10a -79.86 m4: Fnet= Fg - T3 20a= 200 - T3 T3= 200-20a After finding these four equations I just started at the last equation and kept substituting from there.
