Problem 6: Consider the double pulley system in the figure, with
two hanging two masses, where M1 = 59 kg and M2 = 2.5 kg. The
string has a mass density of p = 55 g/m which is much smaller than
either of the hanging masses, and there is no friction in the
pulleys. TT M2 Mi Otheexpertta.com 25% Part (a) Give an expression
for the acceleration of the system, assuming the positive direction
is towards the larger mass. a = ((M-M2 (M + M2))g ✓ Correct! * 25%
Part (b) What would the speed of a wave on this string be, in
meters per second, assuming the string is at rest Part (C) A
student disturbs the string, setting up a wave which travels as
shown in the figure. In the frame of the lab, what is the velocity
(in meters per second, with the positive direction towards the
heavy mass) of the wave on the string after t1 = 1.8 s? vi
