A 6 kg rock is suspended by a massless string from one end of a 6m measuring stick. What is the mass of the measuring stick if it is balanced by a support force at the 1m mark? answer in units of kg. Thanks for any help

Rather than just posting the question, you should post your suggested answer or thoughts as well.

Assume that measuring stick is of umiform mass where is the centre of mass? (C)

Use moments

M1 x L1 = M2 x L2

M1=6 kg
L1=1 m
L2= (i.e C - 1 m)


find M2


I'll keep that it mind. Thank you very much!
