A man with mass m1 = 57 kg stands at the left end of a uniform
boat with mass m2 = 160 kg and a length L = 3.2 m. Let the origin
of our coordinate system be the man’s original location as shown in
the drawing. Assume there is no friction or drag between the boat
and water.
A)What is the location of the center of mass of the system?
B)If the man now walks to the right edge of the boat, what is the
location of the center of mass of the system?
C)After walking to the right edge of the boat, how far has the man
moved from his original location? (What is his new location?)
D)After the man walks to the right edge of the boat, what is the
new location the center of the boat?
E)Now the man walks to the very center of the boat. At what
location does the man end up?
