Answer:
(a)20.65g
(b)0.19m
Explanation:
(a) The total mass would be it's mass per length multiplied by the total lenght
0.355(50 + 23*0.355) = 20.65 g
(b) The center of mass would be at point c where the mass on the left and on the right of c is the same
Hence the mass on the left side would be half of its total mass which is 20.65/2 = 10.32 g
[tex]c(50 + 23c) = 10.32[/tex]
[tex]23c^2 + 50c - 10.32 = 0 [/tex]
[tex]c \approx 0.19m[/tex]
