Argh!! Really stuck!! Please help
Hi all, I'm having a few problems doing practical problems. I can solve some of them but I'm having problems with deaccelleration in particular.. Can you help me solve these problems?
The distance s travelled by a train in t seconds after it applies its brakes is given by http://itsligo.learnonline.ie/filter...18de7c5420.gif. How far has the train travelled before it comes to rest ?
I'm totally stumped by this one but I can do some acceleration questions, such as:
A missile is fired vertically upwards and its height h in metres after time t is given by http://itsligo.learnonline.ie/filter...68c9726d40.gif. Calculate the maximum height reached by the missile.
I know thw anwer to this is 1000.. But I'm lost with deaccelleration..
Can someone please help, thanks in advance.
