Question
Bob wants to do Michael Jackson’s Antigravity
dance move, where he leans forward while keeping his
body fully straight. Alice helps him doing the move by
holding a massless invisible string tied to his back (the
string is horizontal). Model Bob as a uniform straight rod
of mass 50 kg and Alice as a wall (see the figure). If the
coefficient of static friction between Bob’s shoes and the floor is ?? = 0.5,
a) What is the tension in the rope? =250N
b) What is the minimum value of ? above which Bob does not slip? = 45
Please show work for b)
Thank you!
