Questions $20-22$ refer to the following scenario:
What is the impulse during the collision? (A) 10 $\mathrm{N} \cdot \mathrm{s}$ (B) 2 $\mathrm{O} \mathrm{N} \cdot \mathrm{s}$ (C) 3 $\mathrm{O} \mathrm{N} \cdot \mathrm{s}$ (D) 6 $\mathrm{O} \mathrm{N} \cdot \mathrm{s}$

So in this question we have to equal and to equal end. Unlike parallel forces. Unlike parallel forces which constitutes we have to determine which constitutes. So answer for this question will be coupled so let us understand the remaining terms. So torque, torque, it is torque. It is a turning movement about a fixed point. Okay. About a fixed point. And couple can be understand of having to talks, couple can be understand of having to talks in the opposing directions to each other. Okay? And the movement movement? Yes, moment. It is defined as the force multiplier by perpendicular distance, perpendicular distance about any fixed point. Okay, so this will be the moment and this is the torque. So to create rotation motion and couple uh create a complete pure rotation motion about a fixed point and this couple has to equal and unlike parallel forces, so the answer for this question will be a couple and option be it is the correct answer. Okay, so this will be the answer for the question.

Since this question we have a certain force cap, suppose Capital F which is applied to a mass M one which gives an acceleration of 15 m per second squared. So we can write that, We know that force f equals to mass into acceleration. So for for the first situation we can write 15 multiplayer by member. Okay. And for the second situation this same force is applied on the second. Mass which gives an acceleration of 10m per second squared. So this will be equal to the situation. Now two masses are stick together and acceleration produced by the same force. This will be uh M one plus M two particular by acceleration. So from here from here we can calculate mass and one which will be fy 15. And from here we can calculate M two equals two F by 10. So from this equation we can write that F. That is equal to everyone from here. This is equal to F by 15 and M two. This is equal to F by 10 more, played by acceleration A. So from here after solving we get F. That is equal to this. F can be taken out, and after taking L C. M we can get 25 divided by 1 50 acceleration eight. So from here after solving it we get acceleration A. That is equal to six m second minus two. Okay, so this becomes the answer for this problem, and from the given options option is the correct answer for this question. Okay, so this becomes the answer for the question Okay?

Problem 18 In this problem, it is saying that a force F1 is acting on a to Cosima system. So masses two key easy and it produces eggs operational evicted. So if the same force acts on the three Kadima's, what will be the actual reason? So, first, we will calculate the value of F one. So we know that from Newton's second law, From Newton's 2nd Law of Motion, everyone victor his equals two mm into a vector. So what will be the value of a phone victor? So masses to and accept reason is a So this is the value of a phone vector that is to into a not the same force acts on the three KZ. Blog. So we can write F one vector is equals 23 and two letters say that acceleration of in that case is yes victor. So, we have to find the value of a director. We can put the value of a phone vector here. So this will be calls to to a vector. Is it calls to three A death victor? All right. So let me dictate it what it is. Vector is representing. It is representing acceleration ah three KZ block. So, if we move further to solve this expression, so it inspector will be equals to two x 3 the victim. Therefore, acceleration of the Tree. Casey Block will be to buy three a victor. So from the given choice, the characterizes option D. So this is the correct answer for this problem.
