We don't definitively know, but it is worth noting that other great apes, our closest relatives, also do not have tails. Perhaps at some point in the evolution of these primates, tails became useless or even inconvenient. Remember if a certain feature becomes useless natural selection will eventually make it disappear over time. Especially as our ancestors started walking upright on two legs, they balanced themselves well and wouldn't have needed a tail.

How has the evolution of human beings been affected by evolutionary forces?
The question is too broad. Every single little facet of our physiology, anatomy, overall morphology, behaviour and our genes has been shaped and reshaped by genetic drift, natural selection, sexual selection over the past three billion years. Mankind has been working on an understanding of these factors and this history for 150 years, and we're nowhere near having a complete picture of even the single clade of hominids, let alone everything in else in our ancestry. How did we lose our hair? How did we lose our tails? How did we develop bipedality? How did we get such big brains? We know that all these things happened, and we know when they happened, and we have plenty of really fine hypotheses for how they happened - but no definitive explanations.So I'd advise you to do one of two things:- Ask a more specific question, or- Just make something up: your guess is as good as mine.
