a)if the masses are held in place and then released , will they start to move? ------> I know the answer is NO.

b)how much mass would you have to add to m2 to cause the masses to begin to move? ----> The answer should be 2.8kg but I dont know how the book got this answer.

c)If you said no to a) and added the mass that you calculated in b), what would be the acceleration of the masses? ---> answer given in the back of textbook is 5.7 m/s^2

ANY help with this problem would be greatly appreciated!! THANK YOU SO MUCH in advance :)
