Homework Statement
Lets image the following a boat has three people in it
A has a mass of 120lb
B has a mass of 180lb
C has a mass of 160lb
and the boat has a mass of 120lb
also distance from person A to the front of the boat is 2 feet and distance from person A to person B is 8 feet and distance from person B to person C who is at the end of boat is 8 feet. What is the center of mass of the boat
Homework Equations
x = (m_1*x_1 + ...+ m_n * x_n)/M
where is the mass of all 3 people and the boat.
The Attempt at a Solution
the center of mass is then
[tex]x = \frac{120lb \cdot (2) + 180lb \cdot (8) + 160lb \cdot 16 }{120+180+160+120}[/tex]
Is this right?
