Problem 5: A painter (of mass 71 kg) needs to reach out from a scaffolding to paint the side ofa building, so he lays a plank across two bars of the scaffolding, and puts a heavy bucket of mass 27 kgdirectly over one of the bars (see figure). You can assume the plank is massless, and is long enough toreach to the other building.LdIf the bars are separated by a distance 1.5 m, how far, d, from the bar on the the right can the painter walk before the plank starts to fall?d=m9HOMEsin()cos(cotan() asin()tan() П ( ) 7 8acos()E ↑AAL 4 57* 1 2 36atan() acotan()sinh()

Must solve the question completely. Don't solve partially. Skip it pls if u don't want to solve it completely. You must solve the complete question all 6 parts. Otherwise you can skip and let others solve it. But don't solve it partially one or three questions. If you do it, I will dislike for sure.
A student measures the mass of an object with a scale several times, resulting in an average mass m = 11.29 grams. Another student points out that the scale was not “zeroed”, or calibrated to read zero mass with no object on it, before the object was weighed. Without a load, the scale reads 0.08 grams. No one has used the scale since the last measurement. c) What is the correct mass of the object?
