What is the acceleration of the system in terms of m1, m2, and g?

• m2g / m1

• (m1 - m2)g / (m1 + m2)

• (m1 + m2)g / (m1 - m2)

• m1g / m2

When given mass ratios, what is the first step in solving for acceleration?

• Calculate the exact masses

• Use the ratio to express one mass in terms of the other

• Ignore the ratio

• Use a different formula
