It is almost time for the end of term exam and I am looking over my old exams and am confused by one problem. Masses m1,m2,m3,m4 are cnnected together(by a "string") on an incline [tex]theta[/tex] = 22 degrees. m1 and tension = T1(connects m1 and m2) start nearest the bottem of the ramp, and a force F = 30N is pulling on m4 parallel to the ramp. We had to find the acceleration of m2 and the m3 tensions. The acceleration of course is the same for all of them.
I got a = F cos[tex]theta[/tex] / (m4 + m3 + m2 + m1) This got marked wrong, if anyone knows why I would greatly appreciate it. Thank you
