Two masses

Question:

Two masses $\mathrm{m}_{1}=5 \mathrm{~kg}$ and $\mathrm{m}_{2}=4.8 \mathrm{~kg}$ tied to a string are hanging over a light frictionless pulley. What is the acceleration of the masses when they are free to move ? $\left(\mathrm{g}=9.8 \mathrm{~m} / \mathrm{s}^{2}\right)$

  1. $0.2 \mathrm{~m} / \mathrm{s}^{2}$

  2. $9.8 \mathrm{~m} / \mathrm{s}^{2}$

  3. $5 \mathrm{~m} / \mathrm{s}^{2}$

  4. $4.8 \mathrm{~m} / \mathrm{s}^{2}$
