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: ->->->->->->->->->->->-> :
5*9.8=49N
6*9.8=58.8N
Fnet=9.8N
9.8N/11kg=.89m/s^2 with the 6kg descending

• 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: ->->->->->->->->->->->-> :
vF=-1.8+.89m/s^2*1s=.91m/s
vAve=1.35m/s
1.35m
#$&*
• 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: ->->->->->->->->->->->-> :
No they are in opposite directions, system slows down in the first second.
