If mA=7 kg and mB=1 kg, and d1=5 m and d2=6 m, 2 a.) Concept: (NOT FOR CREDIT) Explain roughly where the object's center of mass is located, in relation to the geometrical center of the rectangle (marked with +) b.) Calculate Find the exact location of its center of mass m, Select -Select- to the left of the + Submit Answer Sato the right of the + above the+ below to + 8. -1 points My Notes Ask Your Teacher A spot of paint on a bicycle tire moves in a circular path of radius 0.37 m. When the spot has traveled a linear distance of 1.16 m, through how much angle has the tire rotated? rad E TO11:44 AM

Explanation / Answer

Center of mass of two A will be 2.5m above + and that of two B will be 3m below +

CM = [M1*X1 + M2*X2 ]/ [M1 +M2] = [14*2.5+2*(-2.5)]/[14+2] = 1.875 above the +

8) theta = arc/radius =1.16/0.37 = 3.135 rad
