Well i was also doing that intially measured the horz. Distance and got 3.2cm then i measured the vertical dist. of the image and the ruler showed something around 7cm but the ques stated the the dist to be around 0.44m ..which obivously dont match..so yeah than i scalecd the horz. distance according to the ratio from the image..
For steel I said steel has high tensile strength..etc. Is that okay? I was so freaked out during the exam. I was so stressed and all my classmates found the paper hard. I'm so scared, I'm so scared of a B
I wrote steel is ductile so it can be stretched into wires and rods
Wht did u get for the horizontal velocity? I measure the horizontal distance using a ruler and I got 3.2cm which is 0.032m. I got the time as 0.6s. using that I used S=ut+1/2at2 or s=ut (I don't remember)

Well u had to use v=d/t for horizontal velocity and range was 0.32 m
That question was weird what did you write, I'm afraid my answer is most probably wrong.. TAKE THAT EDEXCEL!
There were probably two ques regarding energy conversion..i wrote that not all the work done would be converted to ke some would be converted to other form something like that..

This was answer for why worksone is more than k.e right ?

Lol may b..as i said it was a very lenghty paper i usually remember most questions but this one is an exception..😂
But may be the ques was refering to the movement of the hand while rowing the boat or doing work rowing the boat i.e kinetic energy while rowing more than that of the ke produced while the boat being moved forward..
