(20%} Problem 5: Consider the double pulley system in the figure= with two hanging two masses= where Ml = 58 kg and .142 = 2.5 kg. The string has a mass density of ,0 = 65 g.'m which is much smaller than either of the hanging masses= and there is no friction in the pulleys. 'I Ithocxpu'ltuxum 25% Part (3.) Give an expression for the acceleration of the system= assuming the positive direction is towards the larger mass. a= [ g ( Ml - M2 ) J ( L11 M2) J Correct! 25% Part (13) What would the speed of a wave on this string be= in meters per second= assuming the string is at rest'.' v\". = 25.38 J Correct! 43' 25% 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 positiTe direction towards the heavy mass) of the wave on the string aer r1 = 1.2 s? Q, 25% Part {d} At what time (in 5) would the wave appear to be momentarily motionless in the frame of the lame?
