Question

2. (50) Two blockn are connected by an Ideal string that rns over an Ideal plley lock 3 hang from the string and Block 2 is on a rough surface, as shown below. Block 2 is aleo being paled by & second rope mock 2 in inititally sliding to the lef, with a.peed of 1.7 ㅹ The weights of Blocks 1 and 2 are 12 N and 25 N, respectively. The tension in the wecond rope, to the rh of Block 2, is 16 N anel is directed 18-above tae horinontal. The coemdents of stathe and kinetle Erleton between the Block 2 and the surface are 0.48 and 0.33, espectively fat (a) What is the tension in the first rope, to the left of Block 2? (b) Is the speed of Block 2 increasing, decreasing, or constant? Explain briefly.v. the Block v)d MLS -7 (c) Suppose instead that Block 2 were sliding to the right, with the same initial speed as befo the tension in the first rope, to the left of Block 2, be GREATER THAN, LESS THAN or EQU tension in part (a)? Do not calculate the new tension; instead, explain your reasoning that heon 6 Ca
