Form K mcq question
Two MCQs, I feel there is a mistake
First MCQ is around question 3-4, a work energy problem, the graph gives you the work, which is 8J, the object mass 0.5 kg initially has a speed of 6 m/s, what is the final speed? I got 8 points something for the final speed. But it is not an option.
Second MCQ is in the middle of mcq, about impulse magnitude J1 J2 J3, and there some force vectors graph, I find the net force for each and rank them, non of the answer match my rank.
