There are two blocks kept on our ruffles on the surface. You're as shown in the figure. This is a hospital and this is second. Look, your muscles are given. Ask em one and I'm horizontal. Force is being applied on them and the tube laws are connected to the line in extensive ill massless of spring attention. T will be developed. The string the leads off the block. Uh, mtg. So the normal reaction off the ground or the block maybe enter. And here it is. And when did you so here. The normal reaction on the ground or the block? Maybe anyone refuse. Normal reactions are given us. And when G and M Doje respectively as a system off the blocks is moving right work. So both of loss will experience forces or friction in backward direction like this. So, first of all the data given then in the values Force IHS 68 120 Newton Mosque M one Yes. Well 0.0 k g mosque M two is 18.0 k g and the coefficient of Canada. Friction between both the blocks in the surface is mucus 0.100 in the first part, we have to draw a free body diagram for each law. So most of all, a free body diagram. F b d all m one and it re meeting on ass. The two forces are acting on it. In that direction of motion, there are only two forces. One is this tension industry and oppose it. Print? Yes, it is the force of friction. F one most fun lies new gay into any. They're more forces acting on the block and one g in the normal reaction. Anyone but these are not considered in the recreation off everybody that because both of them cancel each other. And the motion is along Horizontal No F b deep, all empty again for this. This is the block and there is a force applied on it. Yeah, and in the leftward direction one is ancient p in the spring and never tease the force of friction F two, which is gonna seem you gay into Enter. This is a bitch. I'm g off the block, and this is the normal reaction off the ground. Order the block. So these are the two everybody diagrams blocks Now in the second bar, we have to find the acceleration off the system. So go find acceleration. We simply make the equations of motion. So for the second block force F minus tension D and minus or so friction, we went toe empty. And for the first block, the question will become I see minus just F one. It's going toe m one into it if I add the's Immigration's the Pension we began the fourth this 68 10 Newton minus F one means there's a 0.1 because f one waas new gay into anyone. So and it comes up to be you don't find one into well in tow. 9.8. This is for F one and now have toe new doing to enter mewing toe mu contento so nuclear again, 0.1 in tow, getting for him to planning to 9.8 and equal store by addition of these two and 1% toe well plus city. Okay, so it comes off will be 68 minus 17.64 minus 11.76 Musical 30 A. So the acceleration comes out to be equal to 1.29 nature, but a second a square. This is the answer of the second part of the question. No, The third part. We have to find tension in the strength. Find it. The use This equation t minus F one is going toe and money. Or we can say D minus new G LNG. You see Acquittal M one. Okay, so it becomes day is a particle me, Okay. And McGee Plus and went into it. What? Began? CF 0.1 into 12 in 29 point it less well again into acceleration 1.29 Finally, this answer comes up to be 27.2. Noonan, this is the answer or the third party. Thank you.
