Two masses m1 = 5 kg and m2 = 4.8 kg tied to a string are hanging over a light frictionless pulley. What is the acceleration of the masses when lift free to move? (g = 9.8 m/s2)

Question

Two masses m1 = 5 kg and m2 = 4.8 kg tied to a string are hanging over a light frictionless pulley. What is the acceleration of the masses when lift free to move? (g = 9.8 m/s2) (A) 0.2 m/s2 (B) 9.8 m/s2 (C) 5 m/s2 (D) 4.8 m/s2

a = ((m1-m2/m1+m2)) g = 0.2 m/ s2

Q. 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 lift free to move?
$(g = 9.8 m / s^{2})$

$0.2 m / s^{2}$

$9.8 m / s^{2}$

$5 m / s^{2}$

$4.8 m / s^{2}$

$a = (\frac{m _{1} - m _{2}}{m _{1} + m _{2}}) g = 0.2 m / s^{2}$
