Question

Two bodies of masses 1kg and 2kg are lying in xy plane at (-1,2) and (2,4) respectively. What are the coordinates of the center of mass?

Answer 1

Answer:

Coordinate of center of mass of the system is

$r_{cm} = (1, \frac{10}{3})$

Explanation:

As we know by the formula of COM

$r_{cm} = \frac{m_1r_1 + m_2r_2}{m_1 + m_2}$

so we have

$m_1 = 1 kg$

$m_2 = 2 kg$

here we know that

$r_1 = (-1, 2)$

$r_2 = (2, 4)$

now we have

$r_{cm} = \frac{1(-1, 2) + 2(2, 4)}{1 + 2}$

$r_{cm} = \frac{(-1, 2) + (4, 8)}{3}$

$r_{cm} = \frac{(3, 10}{3}$

$r_{cm} = (1, \frac{10}{3})$
