I Have Just Received This Question = A Car Of Mass 1.2 Tonnes Rolls Down A Hill Which Is 600m Long And Is Inclined At An Angle Of 9 Degrees To The Horizontal. Ignoring The Effects Of Air Resistance And Friction And Assuming The Car To Start From Rest At The Top Of The Hill Calculate Its Speed As It Reaches The Bottom Of The Hill. I Think I Need To Calculate This Using A Vector But I Cant See How I Get The Speed. Please Can Some One Explain This As I Cannot Get My Head Around This Hope Some One Can Help Cheers Mark.
