but the force does not keep acting....the linear motion has to be just goverened by gravity! hence it only moves according to gravity (except in the negligible time duration where the other force acts)
Well write that down as your answer then, I'm off to sleep!

PS: this is a-level maths, don't worry, a question like that won't come up on the tripos!
Well, the maths talk has killed the thread, well done guys (I don't care if it's actually Physics, looks a lot like Mechanics to me )
Yay! Weekend! Though am very scared about novice regatta tomorrow, I hope we don't get totally crapped on. Then BCD...bring on the carnage
Went out with the uni lacrosse men last night, was great fun! Much more fun than the rugby boys, possibly partly because this time there were 8 of each sex, rather than 25 girls and 12 boys. Could keep Clareifornication in business for a term!

any suggestion as to why my forarms are killing me so much? My coach keeps saying it's cos i'm not loose, but i swear i am, and when i go very loose (so that it doesnt hurt) i'm sure i'm not pulling my weight at all!
Also i've been told my wrists only hurt if you are feathering wrongly, is that true?

We went out this morning and I had incredible cramp down my left arm, I asked what I was doing wrong to cause that and apparently I'm a 'white knuckle' rower! I also have blisters on the opposite hand to the other bow-siders, something I'm doing is horribly wrong!
both of you have the same problem. you're suffering from "novice deathgrip". when i was novicing last year, i had the same problem.
happens because both of you are attempting to use your inside hands to take the entire stroke, including using it to transfer power to the legs. and by this i mean you are hardly pulling with your outside hands at all. it's okay at low ratings/work, but once you get to race pace, it'll become crab central.
also, novices in general tend to grip too hard. it's the mark of novice crews. experience of a few more cramps will teach you to relax your grip naturally.
regarding feathering, i've been told that you should be able to just place a flat palm (for your inside hand) on your oar and row an absolutely perfect stroke, i.e. no need to grip. many senior crews can row with their outside hands only just fine.
and you shouldn't be getting outside hand blisters, katie j! tell the other bowsiders that!
baz - any words of wisdom? (BTW, technical question - i've found that i tend to do better when i emphasize pulling with outside hand at catch and switching emphasis to inside hand at about half slide... is that horrendously wrong or something?)

You covered pretty much everything, all I would add is that:
1) people should hold the blade in their fingers, not their palms. It make everything so much sharper, and allows you to ride most minor crams.
2) If you're getting blister of any sort, you're gripping the blade too tight; the blade should sit naturally in your fingers; you don't have to squeeze the life out of it!
re technical question: I tend to use my outside hand at the catch, mainly in order to take advantage of the slingshot motion you get from your shoulder, and then complete the stroke my using my inside hand to pull the blade level and regain balance for the finish.
it wouldnt have made a difference whether you helped me or not....cos i fell asleep this afternoon and missed my supervision, i feel so bad!...and it was the first time ever i'd answered all the questions correctly!

hahahaha.
sorry.
PS: I've never done that and neither has any of my supervision partners, or anyone else I know! You are unique!
Btw Visesh saw on your profile you're doing some Neuroscience thingy...? What's it that you're doing...? Me love the study of the brain tis all especially the medical aspect of it!
