As i was saying i am not good at this at all and its something i need to begin to understand. Would you please be able to provide a worked solution so i can begin to understand. It would be greatly appreciated. Thanks.
Yes i see where you are coming from with that, as u say the answer still comes out to be 0.267m.
Maybe the 0.302m could be wrong however i would be suprised if it was given its come from the lecturer.
I understand that the acceleration is negative as you have said however...
Could somebody please explain the answer then as i am led to believe that the answer is 0.302m, however i am having trouble computing a answer that is even close to the answer.
Thanks for your help.

Thanks for you help.
so when working a) i seem to get ... 0.16 however i believe the answer is 8m/s
should i have done 2.4/(60*.05)=0.8 however have i messed my units up somewhere?
Thanks again.
