Be Careful not to Tip
the Canoe
Due this Friday, Mar 8 at 11:59 pm (EST)
Ric, mass 114.1 kg, and Sharon, who is lighter, are
enjoying Lake Snowden at dusk in a 30.0 kg-canoe.
When the canoe is at rest in the placid water, they
exchange seats, which are 3.0 m apart and
symmetrically located with respect to the canoe's
center. Ric notices that the canoe moved 34.5 cm
relative to a submerged log during the exchange and
calculates Sharon's mass, which she has not told him.
What is it?
