Homework Statement


A pulley with mass Mp and a radius Rp is attached to the ceiling, in a gravity field of 9.81 m/s2 and rotates with no friction about its pivot.
Mass M2 is larger than mass m1. The quantities Tn and g are magnitudes.
1) The magnitude of the acceleration of m1 is ... that of M2.
2) T1 is ... T2;
3) T3 is ... m1g + M2g + Mpg.
4) The C.M. of Mp+M1+M2 accelerates.
5) T3 is ... T1 + T2
6) T1 is ... m1g.
Each has the options of True/False/Less than/Greater than/Equal to

2. The attempt at a solution
1) Equal to
2) Greater than
3) Equal to
4) False
5) Greater than

Hey there -- could you explain your reasoning for each of your answers? It's policy for the forums, and it helps us determine whether your answers are correct.
 
Nevermind! I was able to figure out the answer. It was:
1) equal to
2) less than
3) less than
4) true
5) greater than
6) greater than
 
I think you still have one incorrect answer.
