Sir In the 11 question of two identical bullets, can we use Newton's third law of motion stating that every object will have equal and opposite reaction and thus both the bullets will give the same amount of reaction force on both guns but since one is lighter and the other is heavier, therefore the lighter gun will hurt more
Sir in question 18, is the force negative? Coz in the exemplar solutions, it's positive. In fact when I myself tried to solve it, it came negative only. BTW your explanation for the sprinkler question was really nice. I also wanted to ask whether physics in class 9 would be difficult??
