** CQ_1_12.1_labelMessages **
Masses of 5 kg and 6 kg are suspended from opposite sides of a light frictionless pulley and are released.
• What will be the net force on the 2-mass system and what will be the magnitude and direction of its acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
fnet=11kg*9.8
=107.8N
58.8N-49N=9.8N towards the 6kg weight

• If you give the system a push so that at the instant of release the 5 kg object is descending at 1.8 meters / second, what will be the speed and direction of motion of the 5 kg mass 1 second later?
answer/question/discussion: ->->->->->->->->->->->-> :
9.8 N / (11 kg) = .9 m/s^2.
V0= 1.8 m/s^2
Accelerates at .9 m/s^2 until the velocity is zero.

• During the first second, are the velocity and acceleration of the system in the same direction or in opposite directions, and does the system slow down or speed up?
answer/question/discussion: ->->->->->->->->->->->-> :
the velocity is positive and the acceleration is negative so the system is slowing down, after the velocity will be headed towads zero.
