Question 1 part c
Answer sheet says
I got 0.28m as an answer from the initial position. I have no idea why there is a 2 2/7m written there. Its confusing me so I need a confirmation if my guess is right or not

From it's initial position, B has already travelled 2m from it's initial position when A hits the ground and travels a further 2/7 m before it stops. 2 + 2/7 = 16/7 By keeping the working in exact fractions and in multiples of g rather than rounded decimal approximations you reach the answer 2/7 for additional travel rather than your 0.28

I should have thought. There are some mistakes in the book that is why so thought it could be a mistake too

Aah I I got it now thanks. Its kind of like B will dangle up when A hits the ground right?

As you say there are lots of errors in text books so always worth a check.
