    Hey guys, please help me with this, my answer is ?34 and -?34 can't see why I am wrong, the answer is apparently meant to be 4 and -4 but the answers are sometimes wrong... Anyways the question is...

    A Particle P moves in a straight ling across a horizontal surface with an acceleration of 1.8 meters per second. The particle P passes through a point A with a velocity of 5 meters per second. It then passes through the point B twice, where the distance between A and B is 2.5 meters.

    Thanks for any help guys

    Also, does it tell you which direction the acceleration is acting?

    that is the question... and I assumed by 1.8 it means in the positive direction as the question says it is a horizontal surface... I have triple checked and I reckon that the answer in the book is wrong, it is made by one of our teachers at college and seen as each of our topics has around 30 questions which he has to write and answer himself, generally he tends to make mistakes occasionally.
