WhatAboutTheFinish Posted September 29, 2013 Share Posted September 29, 2013 (edited) I'm maybe over simplifying but.... Kinetic Energy lost = Work done = Force x distance so 0.5 x m x v2 = F x d re-jig that and you to isolate m and you should have your answer!?!

It does give the answer, it's a shorter way of getting the answer I got The numbers in the question seem to be very off for the situation, so perhaps 8.96-18g is correct?

It does give the answer, it's a shorter way of getting the answer I got The numbers in the question seem to be very off for the situation, so perhaps 8.96-18g is correct? Well my answer is low but not that low. I make it to be about 1.5 grams working on the basis that; F = 5530 N d = 0.042 m v ~ 556 m/s I think the difference comes from the way of calculating the velocity. 2000kph is 2000000 metres per hour so then divide that by 3600 (the number of seconds in an hour) to get m/s.

So my first answer was way off... Link to comment Share on other sites More sharing options...

Morpheus Posted September 30, 2013 Share Posted September 30, 2013 Arrived home from holiday last Sunday morning at 2.00am and made the mistake of opening two weeks mail awaiting me rather than getting a good nights sleep first. Contained within one of the letters was a summons from my neighbour taking me to court for alleged harassment and intimidation. No evidence of course in her Affidavit. One accusation is that she can no longer put her washing out in fear of me intimidating her. Took a photo of her yesterday eh putting her washing out.

Popular Post 8pints Posted October 1, 2013 Popular Post Share Posted October 1, 2013 how far would you go if an intruder was in the house ? Depends on how I was feeling and how much I'd had to drink. Probably a kiss on the cheek. 6 Link to comment Share on other sites More sharing options...
