Homework Statement
A mass m1 is pulled along a frictionless horizontal surface by a rope of tension T1, which passes over a pulley of mass mP1 to a hanging pulley of mass mP2, after which it is fixed to the ceiling, as shown in Fig. 1. Labeling the
tension between pulleys 1 and 2 T2, and that between pulley 2 and the ceiling as T3, find the acceleration of the mass
m1. Note that the acceleration of pulley 2 is half the acceleration of m1
The acceleration of m1 is:
(a) 0
(b) [itex]\frac{m(P2)g}{2m1+mP1+(3/4)mP2}[/itex]
(c) [itex]\frac{m(P2)g}{2m1+mP2}[/itex]
(d) g
(e) [itex]\frac{m(P2)g}{2m1+mP1+mP2}[/itex]
Homework Equations
I have no clue
The Attempt at a Solution
when I did it, I got a=[itex]\frac{m2g}{2m1+(m2)/2}[/itex]
But, this is not right. Does it depend on if pulley1 has a mass?
