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

Solution & Step-by-step Explanation

For an Atwood machine, the acceleration a is given by: a = (\frac{m _{1} - m _{2}}{m _{1} + m _{2}}) g Substituting the values: a = (\frac{5 - 4.8}{5 + 4.8}) \times 9.8 a = (\frac{0.2}{9.8}) \times 9.8 = 0.2 m/s^{2}

Try it yourself before checking the explanation above.
