The Atwood machine consists of two masses suspended from a fixed pulley, as shown in Fig.. It is named after the British scientist George Atwood (1746-1807), who used it to study motion and to measure the value of g. If m 1 = 0.55 kg and m 2 = 0.80 kg, (a) what is the acceleration of the system, and (b) what is the magnitude of the tension in the string
