Question

A frictionless, massless pulley is attached to the ceiling, in a gravity field of 9.81 m/s2. Mass M2 is greater than mass m1. The quantities Tn and g are magnitudes.

a.The center of mass accelerates.

b.T1 is ..... M1g.

c. T3 is ..... m1g + M2g

d.T1 is ..... T2

e.The magnitude of the acceleration of M2 is ..... the magnitude of the acceleration on m1.

f. T1 + T2 is ..... T3

**all answers are either true, false, equal to, less than or greater than**

I've already tried:

A.false

B.greater

C.less

D.equal

E. equal

F. equal

and somethings still wrong.
